Description

Zirconium Carbonate Basic CAS NO 37356-18-6 is an inorganic zirconium compound widely used as a versatile precursor and catalyst. Its primary value lies in its ability to provide a controlled source of zirconium oxide (zirconia) upon thermal decomposition, which is critical for creating high-performance materials. This product is essential for manufacturers in the ceramics, catalyst, and specialty chemical industries seeking to enhance product durability, catalytic activity, and surface properties.

Application

• Ceramics & Refractories: Acts as a precursor for zirconia in advanced structural ceramics, thermal barrier coatings, and high-temperature refractory materials.
• Catalyst & Catalyst Support: Used in the preparation of solid acid catalysts and as a support material for various catalytic processes in petrochemical and fine chemical synthesis.
• Opacifier & Pigment: Employed in the production of ceramic glazes, enamels, and pigments to achieve whiteness, opacity, and chemical resistance.
• Precipitating Agent: Functions as an effective precipitating agent for the removal of impurities, particularly in water treatment and hydrometallurgical processes.
• Glass & Optical Coatings: Serves as a component in specialty glasses and thin-film optical coatings to modify refractive index and improve durability.
• Polymer Additive: Used as a flame retardant and smoke suppressant additive in certain polymer formulations.
• Nuclear Industry: Investigated for use in nuclear fuel cycles and waste management due to zirconium's low neutron absorption cross-section.

Quality Control

Our Zirconium Carbonate Basic is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure consistency and compliance with agreed specifications. Key parameters such as zirconium oxide (ZrO₂) content, impurity levels (e.g., Fe, Ti, Si), and physical properties are meticulously controlled. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee traceability and quality assurance for our global B2B clients.

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). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture and carbon dioxide, which can alter the product's properties. Store away from strong acids and incompatible materials.
