Description

Silicon Carbide (SiC) Micron Powder, Purity: 99.5+%, Size: 5–15 μm

Product Description:
Silicon Carbide (SiC) Micron Powder with a purity of 99.5+% and a particle size range of 5–15 μm is a highly durable ceramic-grade material designed for applications requiring superior hardness, thermal stability, and chemical resistance. With its intermediate fine particle size, it offers excellent flowability and uniform dispersion in advanced material formulations.

Its exceptional Mohs hardness of 9.5 and thermal conductivity make it suitable for abrasive systems, refractory components, and ceramic composites where strength and resistance to heat and wear are critical. The material’s high purity ensures minimal contamination and consistent performance in high-temperature and high-stress environments.

Technical Properties:

• SiC: 99%

• Free Carbon: 0.05%

• Aluminum (Al): 0.018%

• Iron (Fe): 0.057%

• Calcium (Ca): 0.050%

• Heating Power: 30.343 KJ/mol

• Hardness: 9.5 Mohs

• Density (288K): 3.216 g/cm³

• Compressibility Coefficient: 0.21 × 10⁻⁶

• Thermal Expansion Coefficient (1173K): 2.98 × 10⁻⁶ K⁻¹

Storage Condition:
Silicon Carbide micron powder should be stored in vacuum-sealed packaging in a cool, dry environment. It must be protected from air exposure and mechanical stress to preserve its structural and chemical integrity.

Applications:

• High-grade refractory components for metallurgy and energy industries

• Advanced ceramic parts: bearings, textile ceramics, insulators

• Abrasive media for polishing, grinding, and lapping operations

• Composite reinforcement to improve strength and thermal resistance

• Heat-resistant nozzles, seals, and mechanical parts

• Substrates and supports for high-frequency or electronic modules

This product is non-radioactive, does not contain heavy metals, and is free from toxic or carcinogenic substances, making it a safe and sustainable material for demanding industrial applications.
