Silicon Carbide SiC Pulp:

SiC Silicon carbide is a lightweight and strong ceramic material that can be used in place of diamonds. Silicon carbide This ceramic material is excellent for applications that require high-temperature resistance, good erosion resistance, and abrasive resistance.

Silicon carbide, Also known by the common name emery (a type of semiconductor), is a silicon carbide semiconductor. Silicon carbide can be very hard. It is made from synthetic carbon and silicon. Silicon carbide Formula chemical The SiC. SiC has been a key material for cutting and grinding tools since the late 19th century.

Microscopic silicon carbide powders are hexagonal crystals. Their Mohs hardness is 9.2, and their Vickers microhardness ranges from 3000-3300kg/mm2, Knoop hardness between 2670-2815.55 kg/mm2, and microhardness measures 3300 mm per cubic meter. It's second only to diamond and cubic boron-nitride in the abrasive industry, surpassing corundum. The silicon carbide abrasive's density is about 3.20 g/cm3. Its natural bulk density, 1.2 to 1.6 g/mm3, is around 3.20 g/cm3. Specific gravity is 3.20 to 3.25. As its primary raw material, green silicon carbide is made from petroleum coke and silica of high quality. Salt is used as an additive. At high temperatures in resistance furnaces, its hardness equals that of diamond. Additionally, it has higher mechanical strength and is harder than corundum.

Silicon carbide ceramic This non-oxide ceramic is suitable for use in many products, which must perform in high thermal (high temperature and thermal shock) and other demanding environments. Single-crystal SiC has better performance. However, it comes at a high cost.

Silicon carbide is made up of an atom-tetrahedron composed of silicon and carbon. There are strong bonds in its crystal lattice. It is very durable. Silicon carbide can withstand acidic, alkali, and molten salts up to 800 degrees Celsius.

Production Method of Silicon Carbide SiC Powder:

Vapor deposition: Vapor deposition is a common method of manufacturing silicon carbide, including chemical vapor deposition (CVD) and physical vapor deposition (PVD), two methods. It is based on natural gas (such as methane, ethane, etc.) and silane as raw materials, and the reaction at high temperatures produces silicon carbide deposited on the matrix. The physical vapor deposition method is to vaporize silicon and carbon monomer at a high temperature and then condense into silicon carbide at a low temperature and deposit on the matrix. High purity, high density, and uniform structure of SIC materials can be produced by vapor deposition, but the production cost is high.

Solid-state carbonization method: The solid-state carbonization method is a traditional method of preparing silicon carbide, which is to heat raw materials such as quartz sand, coke, or wood chips at high temperatures so that silicon and carbon react to produce silicon carbide. This method is simple to operate and low cost, but the product purity is low, and further purification is needed.

Liquid phase method: It is a new method for preparing silicon carbide, which is to dissolve silane and carbon black in a solvent under high temperature and high pressure to form a liquid phase and then react carbon and silicon to generate silicon carbide precipitation by adjusting temperature and pressure and other conditions. This method has the advantages of high product purity, controllable particle size distribution, etc., but the production cost is high.

Laser cladding method: The laser cladding method is a method of rapid manufacturing of silicon carbide, silicon carbide powder, and metal matrix melt mixing under the action of the laser and then rapid cooling solidification to form a high-density, high-hardness silicon carbide coating. This method can produce high-performance silicon carbide coating, but the production efficiency is low.
