F90 F100 green silicon carbide for high-performance carbon/carbon composite materials
F90 F100 green silicon carbide for high-performance carbon/carbon composite materials is an extremely hard (Knoop 2600 or Mohs 9.4) man made mineral that possesses high thermal conductivity (100 W/m-K). It also has high strength at elevated temperatures (at 1000°C, Green SiC is 7.5 times stronger than Al2O3). Green SiC has a modulus of elasticity of 410 GPa, with no decrease in strength up to 1600°C, and it does not melt at normal pressures but instead dissociates at 2815.5°C.

Green SiC offer decisive advantages:
-
Efficient Machining & Grinding: Their extreme hardness allows for effective shaping, grinding, and machining of the notoriously tough C/C composites, reducing processing time and tool wear.
-
Enhanced Surface Integrity: The sharp grains produce clean cuts with minimal subsurface damage, which is crucial for maintaining the structural integrity and fatigue resistance of the final composite component.
-
Superior Thermal & Chemical Resistance: SiC retains its strength and cutting ability at elevated temperatures, making it suitable for processes involving heat. It is also inert, preventing unwanted chemical reactions with the carbon matrix.
-
Consistent Performance: Our rigorous production and grading processes ensure batch-to-batch consistency in particle size, shape, and purity. This reliability is essential for repeatable, high-quality manufacturing outcomes, ensuring every C/C composite part meets stringent specifications.
