The green silicon carbide material has high hardness and strong cutting ability. Because of its stable chemical properties, it has good thermal conductivity.
From the production process point of view, the manufacturing method of green silicon carbide is the same as that of black silicon carbide, and it is also formed at a high temperature of about 2200°C in a resistance furnace. However, in terms of raw material selection, the raw material purity of green silicon carbide is higher. After the smelting is completed, it presents a green translucent hexagonal crystal, and its Sic content is higher than that of black. Although the physical properties of green silicon carbide are similar to black silicon carbide, it is more brittle than black silicon carbide.
The performance of green silicon carbide is destined to be more suitable for grinding cemented carbide and hard and brittle metals, such as copper, brass, aluminum and magnesium. Also suitable for grinding gems, optical glass, ceramics and other non-metallic materials.
The green silicon carbide grinding wheel is a porous body made of green silicon carbide as the raw material, adding various binders to the abrasive, and then compacting, drying and roasting.
Sharp abrasive grains and high hardness are the remarkable advantages of the green silicon carbide grinding wheel, which can grind hard and brittle materials such as cemented carbide, ceramics, optical glass, and alloys. It is also suitable for grinding workpieces that are easily deformed by heat because of its good thermal conductivity. However, the problem of high brittleness also makes the green silicon carbide grinding wheel have the disadvantage of poor edge retention, so it is not suitable for processing workpieces with high toughness.
The green silicon carbide grinding wheel has a wide range of applications and can grind cast iron, non-ferrous metals, hard steel, mild steel, 300 (or 400) series stainless steel, malleable cast steel, high-speed steel, (AlNiCo) magnetic steel, chromium plate, brass and other materials.
