98% Black Carborundum For Terrace Grade Level Abrasive Pickling Removing Impurity

98% black carborundum special for terrace grade level abrasive pickling removing impurity

Product name: black silicon 

 Specification: 240#

Main uses :
1. Abrasives - Silicon carbide has high hardness, chemical stability and certain toughness, so it can be used to manufacture fixed abrasives, coated abrasives and free grinding, so as to process glass, ceramics, stone, cast iron and some non-ferrous metals, cemented carbide, titanium alloy, high speed steel tools and grinding wheels.
Refractory and corrosion-resistant materials-mainly because silicon carbide has a high melting point ( degree of decomposition ), chemical inertness and thermal vibration resistance, so silicon carbide can be used for abrasives, ceramic products used in kilns and saggers, zinc smelting industry vertical cylinder distillation furnace with silicon carbide brick, aluminum electrolytic cell lining, crucible, small pieces of furnace materials and other silicon carbide ceramic products.
3.Chemical industry-Si C can be decomposed in molten steel and react with oxygen and metal oxides in molten steel to form carbon monoxide and silicon-containing slag. Therefore, it can be used as a purifying agent for smelting steel, that is, as a deoxidizer for steelmaking and a modifier for cast iron structure. This generally uses low purity silicon carbide to reduce costs. It can also be used as a raw material for manufacturing silicon tetrachloride.
4.Electrician-used as heating element, nonlinear resistance element and high semiconductor material. Heating elements such as silicon carbon rods ( suitable for various electric furnaces working at 1100 ~ 1500 °C ), nonlinear resistance elements, various types of lightning arrester valves.
