Zirconium tetrachloride (ZrCl4) is an inorganic chloride used mainly as a chemical intermediate and precursor for zirconium metal, zirconia, and other zirconium compounds. Its value comes from the way it can be purified, handled as a feed material, and converted through downstream processes. It is moisture-sensitive, so storage, packaging, and transfer conditions are important parts of any purchasing decision. In this guide, we explain its key properties, industrial uses, material options, and the questions buyers should ask when sourcing it.
Zirconium tetrachloride is a white to off-white crystalline inorganic compound with the formula ZrCl4 and CAS number 10026-11-6. Its molar mass is approximately 233.04 g/mol. Reference sources commonly report a melting point near 437°C, but reported values and observed behavior can depend on material condition and test method.
The compound is sensitive to moisture and can react with water, producing acidic hydrolysis products that include hydrogen chloride. For that reason, exposure to humid air can affect handling and material quality. Buyers should consult the product’s current safety data sheet and follow suitable controls for corrosive, moisture-sensitive chemicals.
ZrCl4 is useful where a zirconium-containing feedstock is needed for a controlled chemical or metallurgical process. Its composition and impurity profile can influence downstream yield, product quality, and process stability. A specification should therefore describe more than the main compound assay: moisture and relevant metallic or non-metallic impurities may also matter.
One major use of zirconium tetrachloride is as a feed material for producing zirconium metal. In the Kroll process, zirconium tetrachloride is reduced with magnesium, with industrial operations commonly conducted at temperatures around 800°C; exact conditions depend on equipment and process design. Metal production requirements can be especially sensitive to contamination, so the buyer should specify limits for impurities that could affect the final metal or its intended use.
Zirconium tetrachloride can serve as a starting material in the preparation of zirconium oxide and other zirconium-containing compounds. The appropriate route depends on the desired product form, particle characteristics, purity, and downstream conversion process. Buyers should identify the final material and process requirements before selecting a grade, rather than assuming one specification fits every zirconium application.
Zirconium compounds are used in catalyst development and other specialized chemical applications, where ZrCl4 may be selected as a zirconium source or precursor. It is also considered in certain vapor-phase deposition processes, including processes designed to form zirconium-containing coatings. Suitability depends on the chemistry, reactor conditions, precursor delivery method, and required film properties, so qualification should be performed by the process owner.
Commercial availability and grade names vary by supplier, so buyers should compare the actual specification rather than relying on labels such as “industrial” or “high purity” alone. A standard process may tolerate impurity levels that would be unsuitable for high-purity metal production or a tightly controlled deposition application. If the process has defined acceptance limits, share them during the quotation stage.

| Specification item | Why it matters | What to confirm |
|---|---|---|
| Assay or purity | Indicates the proportion of the target compound under the supplier’s stated method. | Required value, test method, and whether results are reported on an as-received basis. |
| Moisture or hydrolysis indicators | Moisture exposure can change material condition and handling behavior. | Limit, measurement method, and packaging controls. |
| Elemental impurities | Trace contaminants may affect metal, ceramic, catalyst, or coating performance. | Which elements are controlled and the maximum limits for each. |
| Physical form and packaging | Influences feeding, transfer, storage, and protection from ambient moisture. | Container material, net weight, closure, and inner barrier arrangement. |
Start with the intended use, process conditions, and final product requirements. Identify which impurities are critical, whether moisture has a defined limit, and whether the material must meet a customer or internal specification. For development work, request a sample or a small qualification quantity where available and evaluate it using your own process criteria.
Ask for a current certificate of analysis, safety data sheet, product specification, and available batch traceability information. Confirm that the documents describe the offered grade and that the stated test methods are suitable for your requirements. Also clarify packaging, storage recommendations, transport arrangements, and how the supplier manages moisture-sensitive material.
The price of zirconium tetrachloride is influenced by grade, order volume, packaging requirements, specification limits, and delivery destination. A tighter impurity profile or additional documentation may affect the quoted offer, depending on the supplier’s product and process. Minimum order quantities and lead times are likewise supplier- and order-specific, so they should be confirmed rather than assumed.
For an accurate quotation, provide the required grade or specification, target quantity, preferred packaging, delivery location, and expected order schedule. If the application is new, explain the qualification plan and whether an initial evaluation quantity is needed. These details help suppliers assess the request and identify any technical or logistics questions early.
When comparing suppliers, consider technical communication alongside price. A clear response about specification gaps, packaging, or documentation can help prevent avoidable qualification delays. Buyers should also confirm that the material offered is the same grade and configuration that will be supplied on repeat orders.
Zirconium tetrachloride is a useful industrial intermediate when a process requires a zirconium source for metal production, compound synthesis, catalyst work, or selected deposition applications. Its moisture sensitivity and the potential importance of trace impurities make grade selection and protective handling central to successful sourcing. The best choice is the material whose verified specification fits the actual process—not simply the product with the broadest purity claim.
Before requesting a quotation, define your application, required assay, critical impurity limits, quantity, packaging, and delivery location. At Azeal Materials, we can discuss your zirconium tetrachloride requirements and help clarify the product information needed for a suitable supply proposal.
