Description

Zirconyl Hydroxide is a versatile inorganic compound, primarily known as a key precursor in the production of zirconium-based ceramics and catalysts. Its value lies in its ability to provide a source of reactive zirconium oxide upon controlled thermal decomposition, which is critical for achieving desired material properties. This makes it an essential raw material for industries involved in advanced ceramics, catalysis, and surface treatment technologies.

Application

• Ceramic Precursor: Primary raw material for manufacturing zirconia (ZrO₂) ceramics, including structural components, thermal barrier coatings, and biomedical implants.
• Catalyst & Catalyst Support: Used in the synthesis of solid acid catalysts and as a support material in various organic synthesis and petrochemical processes.
• Opacifier & Pigment: Acts as an opacifying agent in ceramic glazes, enamels, and specialty pigments due to its high refractive index.
• Water Treatment: Employed as an adsorbent for the removal of arsenic, fluoride, and other anions from industrial wastewater.
• Chemical Intermediate: Serves as an intermediate in the production of other zirconium salts, such as zirconyl chloride and zirconium carbonate.
• Polishing Compounds: A component in high-performance polishing slurries for optical glass and semiconductor wafers.
• Flame Retardant Additive: Incorporated into polymers and textiles to enhance flame retardancy and smoke suppression.
• Nuclear Industry: Investigated for use in nuclear waste encapsulation and as a component in certain nuclear fuel cycles.

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) and must be kept in a moisture-free environment to prevent caking and degradation of reactivity. Keep away from strong acids and strong oxidizing agents.
