Black silicon carbide-SiC ceramic product material

Description:

Black silicon carbide is produced by smelting quartz sand, petroleum coke (or coal coke), wood chips, and other raw materials in a resistance furnace. It appears as a black opaque body with hexagonal crystals and a Mohs hardness of 9.15. Second only to diamond and boron carbide, it possesses brittle and sharp properties with a certain degree of conductivity.

Applications for black silicon carbide:

• Abrasives: Primarily used in the production of grinding wheels, sandpaper, oilstones, grinding heads, polishing pastes, and for surface grinding and polishing of monocrystalline silicon, polycrystalline silicon, and various devices in photovoltaic products.
• Advanced refractories: It can serve as a deoxidizer in metallurgy and a high-temperature resistant material for manufacturing high-temperature furnace components and support parts.
• Functional ceramics: Not only can it reduce kiln capacity, but it also improves kiln product quality and shortens cycles. It is ideal for indirect material production of ceramic glaze firing and sintering, high-temperature non-oxide ceramics, and reaction sintered ceramics.
• Non-ferrous metals: Applied in the steel industry, metallurgical ore dressing industry, and more.
