• 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 sealed in a vacuum environment, away from humidity and mechanical stress. Air exposure should be minimized to maintain quality.

Applications:

• Refractory components and kiln linings

• High-strength structural ceramics

• Abrasive products: grinding wheels, lapping powders, and polishing compounds

• Electronic substrate materials and multichip module supports

• Thermal spray coatings and wear-resistant composites

• Components for high-temperature fluid flow and sealing applications

This non-radioactive, heavy-metal-free SiC powder meets environmental safety standards, making it a trusted material for precision manufacturing and research environments alike.
