Description

Zirconyl Sulfate CAS NO 15578-19-5 is an inorganic salt of zirconium, widely recognized for its role as a versatile precursor and catalyst in advanced material synthesis. Its primary commercial value lies in its ability to provide a stable source of zirconium ions for the formation of high-purity zirconia and other zirconium-based compounds. This product is essential for manufacturers and researchers in the ceramics, catalyst, and specialty chemical industries seeking reliable raw materials for high-performance applications.

Application

• Ceramics & Refractories: A key precursor for the production of zirconium dioxide (zirconia), used in advanced structural ceramics, thermal barrier coatings, and refractory materials.
• Catalyst Preparation: Serves as a source material for synthesizing solid acid catalysts and catalyst supports used in petrochemical and fine chemical processes.
• Surface Treatment & Coatings: Utilized in conversion coatings for metal pretreatment and as a component in anti-corrosive or decorative surface finishes.
• Precipitating Agent: Acts as a precipitant in the purification and recovery of various elements and in wastewater treatment processes.
• Textile & Leather Processing: Employed as a mordant in dyeing processes to improve color fastness on fabrics and leather.
• Specialty Chemical Synthesis: Used as an intermediate in the manufacture of other zirconium salts and organometallic compounds.

Quality Control

Our Zirconyl Sulfate is produced under a stringent quality management system to ensure batch-to-batch consistency and reliability. The product undergoes comprehensive analytical testing, including assay (Zirconium content), sulfate content, and impurity profile analysis. Certificates of Analysis (COA) documenting all critical parameters are available for every shipment upon request, providing full traceability and compliance assurance for your processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption and caking. Keep away from incompatible materials such as strong bases.
