Storage Condition:
Silicon carbide micron powder should be sealed under vacuum and stored in a cool, dry environment. It should not be exposed to air and must be protected from mechanical stress.
Applications:
Silicon carbide powder can be used as a hard and high-grade refractory material. It can be used in ceramics such as ceramic bearings, textile ceramics, high-frequency ceramics, and ceramic engine parts. It also can be used in hard discs, polishing abrasives, grinding wheels, and as a support for multichip modules. Silicon carbide powder has also high thermal conductivity. It can be used in high-temperature sealing valves, high-temperature spray nozzles, and high-temperature fluid transport parts. It also can be used in composites to increase strength and heat resistance.
