Description

Zirconium Dioxide CAS NO 1314-23-4 is a highly versatile and thermally stable ceramic oxide, also known as zirconia. Its exceptional properties, including high strength, chemical inertness, and excellent thermal insulation, make it a critical material for advanced industrial applications. This product is essential for manufacturers in the ceramics, refractories, electronics, and biomedical implant sectors seeking reliable, high-performance materials.

Application

• Advanced Ceramics & Refractories: Primary material for high-temperature furnace linings, crucibles, and structural ceramics due to its exceptional thermal shock resistance and melting point.
• Biomedical Implants & Prosthetics: Used in the production of durable, biocompatible components for dental crowns, bridges, and orthopedic implants like hip and knee replacements.
• Electronics & Sensors: Key component in oxygen sensors (lambda sensors) for automotive and industrial applications, solid oxide fuel cells (SOFCs), and piezoelectric devices.
• Abrasive & Polishing Compounds: Employed as a high-performance abrasive grain in grinding wheels, sandpapers, and precision optical polishing slurries.
• Catalyst & Catalyst Support: Serves as an inert, high-surface-area support material or as an active catalyst in various chemical synthesis and petrochemical processes.
• Protective Coatings & Thermal Barrier Coatings (TBCs): Applied via plasma spraying to protect turbine blades and engine components from extreme heat and corrosion.
• Pigments & Opacifiers: Used in the ceramics and paint industries to provide bright white color, opacity, and UV resistance in glazes, enamels, and coatings.
• Precision Engineering: Fabricated into wear-resistant parts, cutting tools, and precision ball valves for demanding mechanical and chemical environments.
