Effect of black silicon carbide :
1. Abrasive : Foreign light industrial black silicon carbide is mainly used for abrasive. Process black silicon carbide is in a high position and a certain toughness, mostly used for grinding optical glass, cemented carbide, titanium alloy and bearing steel grinding and polishing, high-speed steel tool grinding ; black silicon carbide is mostly used to cut and grind materials with low tensile strength.
2. Refractory : Black silicon carbide is a kind of high-quality refractory because of its good thermal shock resistance. According to the consumption process of the product is not the same, can be divided into red recrystallized black silicon carbide, products, high temperature hot pressing products, silicon nitride or perhaps clay as a binder products. The main products and uses are : high temperature furnace components, supporting parts.
3.Electric appliance industry : In addition to various smelting furnace lining, it is also used as steelmaking deoxidizer and cast iron structure modifier. The requirements of the chemical elements of black black silicon carbide are as follows : compared with the traditional steelmaking process in which coke and silicon powder are used to suspend evacuation and deoxidization, the use of detachment agent has the advantages of good steel quality and good resting environment.
4.Other areas : electrical industry, black silicon carbide materials are also widely used as electric heating elements, high temperature semi-superconducting materials, far infrared ray plates, arrester valve materials.
