Description

Zirconium Hydroxide is a versatile inorganic compound with the CAS number 14475-63-9, widely used as a precursor and functional material. Its primary value lies in its high surface area, amphoteric nature, and ability to form stable complexes, making it a critical intermediate in advanced material synthesis. This product is essential for manufacturers in the ceramics, catalyst, and specialty chemical industries seeking high-purity raw materials for performance-driven applications.

Application

• Catalyst & Catalyst Support: Acts as a precursor for zirconia-based catalysts used in petroleum refining, automotive exhaust systems, and fine chemical synthesis.
• Ceramics & Refractories: Serves as a key raw material for producing high-performance zirconia ceramics, offering excellent thermal stability and mechanical strength.
• Precipitating Agent & Ion Exchanger: Utilized in water treatment and hydrometallurgy for the selective removal of ions like arsenic, phosphate, and fluoride.
• Polymer Additive & Flame Retardant: Incorporated into polymers to enhance thermal stability, smoke suppression, and mechanical properties.
• Precursor for Zirconium Chemicals: The fundamental starting material for manufacturing various zirconium salts, including zirconium oxychloride and zirconium acetate.
• Optical Coatings & Thin Films: Used in sol-gel processes to deposit transparent, hard, and refractive coatings on glass and optical components.
• Biomedical & Dental Materials: Employed in the research and development of biocompatible coatings for implants and advanced dental ceramics.
• Nuclear Industry: Investigated for applications in nuclear fuel cladding and waste containment due to zirconium's low neutron absorption cross-section.

Quality Control

Our Zirconium Hydroxide is produced under a stringent quality management system to ensure batch-to-batch consistency and high purity. We provide comprehensive analytical data, including assays for zirconium content and key impurity profiles (e.g., heavy metals, chloride, sulfate). A Certificate of Analysis (COA) detailing all test results is available with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept in a cool, dry place with low humidity. Recommended storage temperature is between 15°C and 25°C. Ensure the storage area is well-ventilated and separate from strong acids.
