Metallurgical silicon carbide (SiC), commonly known as diamond sand, is a type of industrial silicon carbide that comes in black and green colors. Widely used in metallurgy, abrasives and grinding
tools, refractory materials, semiconductors, ceramics, new energy and other fields.
Metallurgical industry
Abrasive grade silicon carbide has the functions of increasing silicon, increasing carbon, and reducing oxygen. Compared with traditional carbonization agents, ferrosilicon, and deoxidizers, the
deoxidization is more thorough, greatly increasing the concentration of molten steel. Compared to a single auxiliary material, the overall effect is improved and the overall cost is reduced.
Foundry industry
Granular silicon carbide can optimize graphite morphology, refine crystal structure, and enhance the mechanical properties of castings.
Abrasive and grinding tools
Silicon carbide has the characteristic of high strength. This characteristic can be used to produce grinding wheels, sandpapers, sand belts, oilstones, grinding blocks, grinding heads, grinding
pastes, as well as grinding and polishing of monocrystalline silicon, polycrystalline silicon, and piezoelectric crystals in the electronics industry in photovoltaic products.
High end ceramics&structural materials
Silicon carbide ceramics belong to advanced ceramics, with advantages of high temperature resistance, wear resistance, corrosion resistance, and lightweight. In the industrial field, they include
kiln furniture, high-temperature crucibles, mechanical seals, wear-resistant pipelines, and pump body accessories; Civilian field: high-end kitchenware (wear-resistant non stick coating substrate),
bulletproof armor, aerospace lightweight structural components.
Semiconductor&Electronic New Energy
High purity silicon carbide is the third-generation semiconductor core substrate, which has developed rapidly in recent years. It is used to produce silicon carbide wafers and power devices
(MOSFET, IGBT), with the characteristics of high voltage resistance, low loss, high temperature resistance, and good high-frequency performance; Main applications: New energy vehicle onboard power
supply, charging piles, photovoltaic inverters, rail transit, energy storage equipment, 5G base stations, are key materials in the new energy industry.
