Description

Zirconium Oxide CAS NO 11129-15-0 is a high-performance ceramic material, also known as zirconia, prized for its exceptional thermal stability, mechanical strength, and chemical inertness. Its unique combination of properties makes it a critical component in demanding industrial and technological applications where reliability under extreme conditions is paramount. This material is essential for manufacturers and R&D facilities in the advanced ceramics, refractory, electronics, and biomedical implant sectors.

Application

• Advanced Structural Ceramics: Key component in high-strength, wear-resistant parts for pumps, valves, and cutting tools.
• Refractory Materials: Used in furnace linings, crucibles, and thermal barrier coatings due to its extremely high melting point and thermal shock resistance.
• Electronics & Sensors: Serves as a substrate for thin-film circuits, a component in oxygen sensors (lambda sensors), and in solid oxide fuel cells (SOFCs).
• Biomedical Implants: Utilized in dental crowns, bridges, and orthopedic implants for its biocompatibility, strength, and aesthetic qualities.
• Catalysts & Catalyst Supports: Acts as a catalyst itself or as a stable, inert support material in various chemical processes.
• Abrasive & Polishing Compounds: Employed in precision polishing slurries for optical lenses, semiconductors, and hard surfaces.
• Pigments & Glazes: Provides opacity, brightness, and durability in high-temperature ceramic glazes and specialty pigments.

Quality Control

Our Zirconium Oxide is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. We provide material that can meet various industrial and technical grade specifications, with parameters such as crystalline phase (monoclinic, tetragonal), particle size distribution, and impurity levels tightly controlled. A Certificate of Analysis (COA) detailing specific lot results is available for every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from incompatible materials. The product is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent moisture absorption.
