Green silicon carbide powder is a common wire-sawing material in the photovoltaic industry. In recent years, the photovoltaic industry has significantly shrunk, and wire sawing is mainly used for slicing silicon wafers in the semiconductor industry. Diamond wire made from SiC powder combined with steel wire and diamond powder has become the two main tools for chip sawing. The differences between the two wire sawing methods are:

In semiconductor production equipment, high-performance ceramic components are essential. Especially silicon carbide ceramics are important components in key equipment such as etching machines, lithography machines, ion implantation machines, etc. For example, grinding and polishing suction cups, photolithography suction cups, inspection suction cups, etching processes, and motion platforms all have the presence of silicon carbide ceramics. These silicon carbide ceramic components have good structural stability, thermal stability, wear resistance, corrosion resistance, and high dimensional accuracy. Silicon carbide powder, as the main raw material for producing silicon carbide ceramics, must also have good and stable properties. Among them,  black SiC powder 800# for porous silicon carbide ceramic suction cups is a typical application.

Resin-bonded superabrasives are grinding tools made mainly from artificial diamond or cubic boron nitride as the main raw materials. In addition to superabrasive materials, filling materials are often added to superhard grinding tools to achieve reinforcement, increase porosity, and reduce costs. Green SiC powder, as a filling material for superhard grinding tools, has the following functions and advantages:

Reshaped Green silicon carbide 100 # grit is processed by special crushing and sand-making processes. The bulk density is higher than ordinary green silicon carbide grain with more round particles. When producing silicon carbide ceramic parts, adding more silicon carbide to the same container is beneficial for improving the density and mechanical strength of bulletproof ceramics. The difference between the two is shown in the following figure:

Silicon carbide powder is a high-hardness non-metallic abrasive product. It is second only to diamond in hardness in synthetic materials. There are few silicon carbide materials in the natural minerals. In the meantime, the use in the industrial field covers a large range. Silicon carbide is an important industry related to the national economy and people’s livelihood. Therefore, smelting production through the Acheson process is an inevitable choice for the production of silicon carbide abrasives. However, the production industry and equipment of silicon carbide are complex and consume a large amount of electricity. Chinese silicon carbide abrasive manufacturers have explored step by step, and currently, China’s silicon carbide abrasive production capacity accounts for over 80% of the world’s.
