Silicon carbide whisker is a kind of high-strength whisker-like (one-dimensional) single crystal with many excellent mechanical properties such as high strength and high modulus. Mainly used in ceramics, high-temperature components in the aerospace field, main strong bearing blocks, large mud pumps, etc.

Physical characteristics: It is cubic crystal type, which belongs to the same crystal type as diamond.
Chemical characteristics: wear resistance, high temperature resistance, special thermal shock resistance, corrosion resistance, radiation resistance;
Applications: high-grade ceramic bearings, molds, high-pressure jet nozzles, high-temperature coatings, etc .;
As a reinforcing component, it is added to a plastic substrate, a metal substrate, or a ceramic substrate to play a role of strengthening and toughening. It uses the high thermal conductivity, high insulation of Sic materials, and is used as a substrate and packaging material for large-scale integrated circuits in the electronics industry. As information optical materials, it has high application value in the fields of television display, modern communication, and network.
At the same time, silicon carbide whiskers are used in the manufacture of high-strength plastics, metals and ceramics to accelerate the upgrading of key traditional products. Due to the excellent function of silicon carbide whiskers, it has a special role in the aerospace industry industry, that is, the application on the shell and the application of engines, high-temperature turbine rotors, and special components, so it is in great demand in the military and civilian industries .
Regarding the dispersion of silicon carbide whiskers:
Silicon carbide SiC whiskers are gray-green powder in a macroscopic view. Only when they are evenly distributed in the matrix material, can they strengthen and toughen the effect. For this reason, we must focus on the dispersion of whiskers during use. Its dispersion steps are:
1] Select the dispersion medium. Water, ethanol, isopropanol, etc. are all acceptable.
2] Select dispersant.
3] Adjust the pH of the dispersion medium. Generally, it can be adjusted to 8.
4] Stir well
Silicon carbide whisker is a kind of single crystal fiber with few defects and a certain aspect ratio. It has quite good high temperature resistance and high strength. Silicon carbide whiskers are mainly used for toughening applications that require high temperature and high strength applications. Such as: aerospace materials, high-speed cutting tools, etc.
