Zirconium tetrachloride (ZrCl4) is a moisture-sensitive inorganic compound used mainly as an intermediate for producing zirconium metal and other zirconium chemicals. It is also considered for catalyst and materials processes where a reactive zirconium source is required. Its molecular mass is approximately 233.04 g/mol, and it is commonly described as a white to off-white crystalline solid that can sublime when heated. This guide explains its key properties, industrial uses, purchasing considerations, and the information buyers should confirm with a supplier.

This guide is intended for procurement teams, chemical manufacturers, metallurgical processors, research and development groups, and industrial users evaluating zirconium tetrachloride. It can help buyers distinguish general-purpose material requirements from applications that may need tighter controls on purity, moisture, or trace elements. Because specifications and process conditions vary, the information here is a starting point rather than a substitute for a product specification, safety data sheet, or process review. Buyers should confirm suitability for their intended use before placing an order.
Zirconium tetrachloride has the chemical formula ZrCl4 and consists of zirconium and chlorine. It is generally supplied as a solid and is moisture-sensitive, so exposure to humid air can cause hydrolysis and release hydrogen chloride-containing fumes. This reactivity affects storage, packaging, sampling, and handling, especially in facilities where moisture control is important. Buyers should consult the supplier’s safety documentation for the specific grade and handling instructions.
Reported thermal behavior depends on test conditions and material form. ZrCl4 is often described as subliming at about 331°C under atmospheric conditions, rather than behaving like a simple liquid with a routinely applicable boiling point. Its molecular mass is approximately 233.04 g/mol, a useful value for stoichiometric calculations. A stated value such as density or phase-transition temperature should be checked against the supplier’s current technical documentation and the conditions under which it was measured.
Commercial availability may include different purity levels, impurity limits, and packaging formats, but names such as “technical grade” or “high purity” do not guarantee identical specifications across suppliers. For zirconium tetrachloride, buyers should identify the actual assay method and limits for relevant impurities rather than relying on a grade label alone. Trace hafnium can be an important consideration for some zirconium applications, while moisture and other metallic impurities may matter in process-sensitive uses. Ask for the specification and certificate of analysis applicable to the offered batch.
A major industrial role of ZrCl4 is as a feed material in zirconium metal production. In a common reduction route, zirconium tetrachloride is reduced with magnesium to produce zirconium and magnesium chloride; process design and feed requirements depend on the producer’s equipment and operating conditions. For this use, buyers typically need to discuss chemical purity, consistency between lots, moisture protection, and any limits on hafnium or other elements. The appropriate grade should be determined against the downstream process specification.
ZrCl4 can serve as a starting material for preparing other zirconium compounds, including materials used in ceramics and specialty chemical production. It may also be used as a zirconium source in selected catalyst or synthesis processes, where its Lewis-acid character and reactivity can be relevant. These applications are not interchangeable: a synthesis route may demand a different impurity profile or handling format from a metal-production process. Buyers should share the intended reaction or product requirement when requesting a recommendation.
Start with the output you need, then work backward to the feedstock limits that protect yield, product quality, and equipment operation. For metal production, confirm whether the process specifies hafnium and other trace-element limits. For chemical synthesis, establish acceptable moisture, assay, and impurity levels, as well as whether the material must be supplied in a particular particle form or package size. If the process specification is not yet finalized, request a discussion with the supplier before treating a general commercial grade as suitable.

A complete inquiry should describe the application and identify the properties that are critical to acceptance. Request a written specification covering assay, relevant impurities, appearance, moisture or hydrolysis-related controls where applicable, test methods, and batch documentation. If hafnium content is important, state the required limit explicitly and ask how it is measured. Avoid comparing quotations on price alone when suppliers are offering products with different limits or analytical methods.
| Purchase consideration | What to confirm | Why it matters |
|---|---|---|
| Purity and impurities | Assay basis, trace-element limits, and test methods | Supports comparison against process and product requirements |
| Moisture protection | Packaging, sealing, storage instructions, and sampling controls | Reduces exposure to humidity during handling and transport |
| Documentation | Current SDS, specification, and batch certificate availability | Helps assess safe handling and incoming quality requirements |
| Supply terms | Pack size, minimum order quantity, lead time, and shipping route | Allows realistic planning for trials and repeat procurement |
Because ZrCl4 reacts with moisture, the packaging must be suitable for the product and intended shipping conditions. Confirm that the proposed container is sealed appropriately and that the supplier provides clear instructions for storage, opening, sampling, and disposal. In the receiving facility, handling procedures should follow the product-specific SDS and applicable workplace requirements. Do not assume that a package can be opened safely in an ordinary ambient environment.
Transportation classification and shipping requirements should be verified for the exact product, packaging, route, and destination. Ask the supplier to provide relevant transport and safety documentation before shipment rather than relying on a generic description of the chemical. The buyer should also confirm that staff have suitable training and controls for corrosive, moisture-reactive materials. Any emergency planning should be based on the current SDS and local regulations.
The price of zirconium tetrachloride can vary with purity requirements, impurity limits, order quantity, packaging, and shipment destination. Specialty limits, such as tighter control of hafnium or moisture, may affect the available offer and should be stated in the request for quotation. Minimum order quantity and lead time are supplier- and order-specific, so they should be confirmed rather than assumed from a general product listing. For planning, buyers can request separate quotations for an evaluation quantity and anticipated repeat volume.
To make quotations comparable, provide the required grade or specification, quantity, package preference, destination, and target delivery window. Ask whether the quoted price includes packaging and what documentation accompanies each batch. If the material is for a qualification trial, clarify whether the same specification and packaging can be maintained for future production orders. These details help reduce uncertainty during technical approval and procurement.
A supplier’s response should be specific enough for technical and procurement teams to assess the offered product against their needs. Look for clear documentation and consistent answers about grade, packaging, and order terms. If a critical requirement cannot be confirmed, resolve it before purchase or qualification. A transparent specification is more useful than an unsupported assurance that a material is suitable for every application.
At Azeal Materials, we work with B2B buyers to clarify zirconium tetrachloride requirements before quotation. Share the application, target specification, quantity, destination, packaging preference, and delivery schedule so we can review the request and confirm available options. We can also help identify which details—such as assay, hafnium, moisture protection, or batch documentation—should be stated explicitly. Availability, minimum order quantity, and lead time are confirmed for each inquiry.
Zirconium tetrachloride is a moisture-sensitive zirconium intermediate used in metal production, chemical synthesis, and selected materials or catalyst processes. The right purchase depends on matching the grade and impurity limits to the process, while also confirming suitable packaging, handling documentation, and supply terms. Before ordering, provide a written specification and ask the supplier to confirm the offered batch against it. Contact Azeal Materials with your application and procurement requirements to discuss a quotation and determine the next steps.
