Description

Silicon Carbide (SiC) Micron Powder, Purity: 99.5+%, Size: 20–50 μm

Product Description:
Silicon Carbide (SiC) Micron Powder with a particle size range of 20–50 μm and 99.5+% purity is a high-performance ceramic-grade powder designed for demanding industrial applications. Its extremely high hardness (9.5 Mohs), excellent thermal conductivity, and impressive chemical inertness make it ideal for environments requiring abrasion resistance, high-temperature stability, and structural integrity.

This particle size range strikes a balance between flowability and packing density, making it especially suitable for use in technical ceramics, abrasive materials, and wear-resistant coatings. The powder is non-toxic, free of heavy metals and radioactive elements, and maintains mechanical and chemical performance in aggressive conditions.

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 (at 288 K): 3.216 g/cm³

• Compressibility Coefficient: 0.21 × 10⁻⁶

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

Storage Condition:
Store in vacuum-sealed packaging in a cool, dry environment. Avoid contact with air and mechanical stress to preserve material integrity.

Applications:

• Advanced refractory materials and linings in high-temperature furnaces

• Technical ceramics including high-frequency insulators, bearings, and structural components
