Description

Zirconium Sulfate is an important inorganic zirconium salt widely used in industrial catalysis and materials processing. Its primary value lies in its role as a versatile precursor for zirconium-based compounds and as a catalyst or catalyst support in specialized chemical reactions. This product is essential for manufacturers and R&D facilities in the chemical, ceramic, and catalyst industries seeking a reliable source of high-purity zirconium compounds.

Application

• Catalyst & Catalyst Support: Used in the preparation of solid acid catalysts for organic synthesis, esterification, and alkylation reactions.
• Ceramics & Glazes: Acts as a precursor for zirconia (ZrO₂) and as an opacifier or stabilizer in specialty ceramic formulations and surface coatings.
• Textile & Leather Processing: Employed as a mordant in dyeing processes to improve color fastness on fabrics and leather.
• Water Treatment: Functions as a coagulant aid or in the formulation of materials for phosphate removal and other purification processes.
• Chemical Synthesis: Serves as a starting material for the synthesis of other zirconium salts, complexes, and advanced materials.
• Surface Treatment: Used in conversion coatings and surface preparation for metals to enhance corrosion resistance and paint adhesion.

Quality Control

Our Zirconium Sulfate is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure consistent purity and meets the specifications required for industrial and research applications. A Certificate of Analysis (COA) detailing key parameters such as zirconium content, sulfate content, and impurity levels is provided with every shipment to guarantee traceability and quality assurance.

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 opening to prevent moisture absorption and caking.
