Green silicon carbide fine sand for solar wire cutting in photovoltaic industry

The production method of green silicon carbide is basically the same as that of black silicon carbide. It is a green translucent crystal with high purity and brittleness. The abrasive tools made of it are suitable for processing materials with high hardness and brittleness, such as cemented carbide, glass, agate, etc. Green silicon carbide is also used as a high-grade refractory, used in electric heating elements and electrical components.
It is mainly used for wire cutting of 3-12 inch single crystal silicon, polycrystalline silicon, potassium arsenide, quartz crystal, etc. Solar photovoltaic industry, semiconductor industry, piezoelectric crystal industry engineering processing materials.
Main features:
1. High purity and large crystalline silicon carbide raw materials ensure excellent cutting performance and stable physical state of silicon carbide cutting micro powder.
2. The grain size is equal product and has edge, which ensures the balanced self sharpening of SiC powder as cutting edge material, so as to ensure the minimum TTV of the material to be cut.
3. The particle size distribution is concentrated and uniform.
4. It has high thermal shock stability and load softening temperature, which ensures small linear expansion coefficient when cutting under load, so as to ensure cutting stability; and it can be well adapted to cutting machine.
5. After special surface treatment, the micro powder has a large specific surface area and clean appearance, and has a good compatibility with polyethylene glycol cutting fluid.
