Green silicon carbide powder

Introduction to green silicon carbide powder:

Green silicon carbide is made by smelting quartz sand, petroleum coke (or coal coke) and wood chips in an electric resistance furnace at high temperature. Green silicon carbide micro powder is made of high-quality green silicon carbide primary block by crushing, screening, grinding, water separation (wind separation) classification, pickling, purification and drying.

Features of green silicon carbide powder:

Physical properties of green silicon carbide powder: green silicon carbide is green, with uniform particle size, crystal structure, high hardness, high brittleness, strong self sharpening, strong cutting force, stable chemical properties, and good thermal conductivity. The microhardness is 3280-3400kg/m ㎡. It is a kind of super hard material, its hardness is only inferior to diamond, and it is resistant to high temperature, acid and alkali.

Executive standard of silicon carbide:

European Standard (F230-F1200); Japanese standard (# 240 - # 6000); W series (W63-W1.5).

Use of green silicon carbide powder:

Green silicon carbide powder has good self sharpening and excellent grinding and polishing properties. It is an engineering processing material for solar silicon photovoltaic industry, semiconductor silicon chip industry and piezoelectric crystal industry.

Green silicon carbide micro powder can be used for wire cutting and precision grinding of 3-12 inch monocrystalline silicon chips, polycrystalline silicon rods, potassium arsenide, quartz crystal chips, processing of superhard metals, processing of soft metals such as copper and copper alloys, and processing of various resin materials. It can be used as consolidation abrasives, coating abrasives, cutting, free grinding and polishing, etc. Suitable for casting, hard alloy, titanium alloy, high speed steel, etc. It can also be used for polishing non-metallic materials such as hard glass, ceramics, crystals, stone semiconductors, agates, jewelry and jades, and pure grain iron; Precision polishing of special steel; And other manufacturing refractory materials, engineering ceramics, heating elements and thermal energy elements, new light pressure resistant building materials, foam ceramic additives.

In the process of selecting green silicon carbide particles, attention should be paid to: silicon carbide content, silicon carbide particle size, silicon carbide glossiness, and the use effect of silicon carbide.
