Product Description

High-Purity Ultrafine Silicon Carbide (SiC) Micropowder for Advanced Ceramics

Our high-purity ultrafine Silicon Carbide (SiC) Micropowder is the premier raw material for manufacturing pressureless-sintered silicon carbide (SSIC) ceramics. Engineered for excellence, it delivers superior wear resistance, exceptional chemical stability, and high-temperature strength, making it ideal for demanding industrial applications.

Key Specifications & Features

High Purity: Exceeds 98.5% purity, ensuring consistent and reliable performance in final ceramic products.
Ultrafine Particle Size: Controlled D50 particle size of 0.5 - 0.7 μm with a narrow distribution for enhanced sinterability and superior final density.
Large Specific Surface Area: Promotes higher reaction efficiency and improved material properties during sintering.
High Surface Activity: Facilitates better compounding and interfacial bonding with other materials.
Exceptional Hardness: Mohs hardness of 9.3-9.5, second only to diamond, providing outstanding wear and abrasion resistance.
Superior Chemical Stability: Excellent resistance to oxidation, acids, alkalis, and corrosion, suitable for harsh environments.

Primary Advantages

Optimized for Sintering: The ultrafine and uniform particle morphology is specifically designed to produce high-density, high-performance SSIC ceramics via pressureless sintering.
