Silicon carbide due to stable chemical properties, high thermal conductivity, small thermal expansion coefficient, good wear resistance, in addition to abrasives, there are many other uses, such as: silicon carbide powder coated on the inner wall of the turbine impeller or cylinder block by a special process, which can improve its wear resistance and extend the service life by 1~2 times;
Black Silicon Carbide Abrasives Grits is made according to China GB/Japan JIS/American ANSI/Europe FEPA
Black silicon carbide sand is suitable for grinding materials with low tensile strength, such as gray cast iron, non-ferrous metal pure aluminum, aluminum alloy, brass, cupronickel, red copper and other materials with relatively high viscosity, as well as stone, ceramic glass, refractory materials, etc.
Emery, also known as silicon carbide, includes black silicon carbide and green silicon carbide, among which: black silicon carbide is made of quartz sand, petroleum coke and high-quality silica as the main raw materials, and is smelted by resistance furnace at high temperature. Its hardness is between corundum and diamond, its mechanical strength is higher than that of corundum, and it is brittle and sharp.
Black silicon carbide is made of quartz sand, petroleum coke (or coal coke), wood chips and other raw materials in a resistance furnace by high temperature smelting, black opaque body, hexagonal crystal, Mohs hardness of 9.15.
Black silicon carbide is made of quartz sand, petroleum coke (or coal coke), wood chips and other raw materials through high-temperature smelting in a resistance furnace. It is black opaque, hexagonal crystal, and the Mohs hardness is 9.15.
Silicon carbide honeycomb ceramics are honeycomb ceramics with silicon carbide (sic) as the main component.
It is black, brittle and sharp, and has good thermal and electrical conductivity.The microscopic shape is hexagonal crystal, the Mohs hardness of silicon carbide is 9.2, the Microdense hardness of Vickers is 3000–3300kg/mm2, the hardness of Knoop is 2670–2815kg/mm, and the microhardness is 3300kg/mm3.Higher than corundum in abrasives and second only to diamond, cubic boron nitride and boron carbide.
White corundum It is made of high-quality aluminum oxide powder as raw material, white corundum is crystallized by electromelting, high purity, good self-sharpening, acid and alkali corrosion resistance, high temperature resistance, stable thermal performance.
As a mineral resource with good performance, black silicon carbide can be used in different fields according to its performance, and how is it used in the field of nuclear power? In order to better understand its application functions, let’s introduce its application in the field of nuclear power.
