Application of silicon carbide powder in abrasives

As a casting material, silicon carbide also plays an important role in abrasives. Silicon carbide has four main application areas, namely: functional ceramics, advanced refractory materials, abrasives and metallurgical raw materials. Silicon carbide rough materials can be supplied in large quantities and cannot be considered high-tech products. However, the application of nano-scale silicon carbide powder with extremely high technical content is unlikely to achieve economies of scale in a short time.

As an abrasive, it can be used to make abrasive tools, such as grinding wheels, whetstones, grinding heads, sand tiles, etc.

Abrasive abrasives are mainly used for grinding and polishing grinding wheels, sandpaper, abrasive belts, whetstones, grinding blocks, grinding heads, abrasive pastes, and monocrystalline silicon, polycrystalline silicon in photovoltaic products, and piezoelectric crystals in the electronics industry. It is used as abrasives for abrasive tools. The general particle sizes are: 60 mesh-80 mesh, 80 mesh-100 mesh, 100 mesh-120 mesh, 120 mesh-140 mesh, 140 mesh-160 mesh, 160 mesh-200 mesh, etc. It is required to be very fine and uniform, and the particle size is very different from ordinary silicon carbide for casting and steelmaking.

Silicon carbide can also be used for wire cutting of 3-12-inch monocrystalline silicon, polycrystalline silicon, potassium arsenide, quartz crystal, etc. Engineering processing materials for solar photovoltaic industry, semiconductor industry, and piezoelectric crystal industry.

Used in semiconductors, lightning rods, circuit components, high temperature applications, UV detectors, structural materials, astronomy, disc brakes, clutches, diesel particulate filters, filament pyrometers, ceramic membranes, cutting tools, heating elements, nuclear fuel , jewelry, steel, protective gear, catalyst carrier and other fields.
