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