Pressureless SSiC Silicon Carbide Spacer

SSiC Spacer Ring Application :
The original application of SiC is widely used in the machining industry due to its super-hardness properties, which can be used for grinding wheels, abrasive cloths, sandpaper and various abrasives. It was also discovered in the Second World War as a reducing agent and heating element in steel making, which promoted the rapid development of SiC. SiC ceramics have been widely used in petroleum, chemical, microelectronics, automotive, aerospace, aerospace, paper, laser, mining and atomic energy industries. Silicon carbide has been widely used in high temperature bearings, bulletproof plates, nozzles, high temperature corrosion resistant parts. And in the field of electronic equipment parts in the high temperature and high frequency range.

Silicon Carbide Ceramic Spacer Advantages :
SiC ceramics not only have excellent mechanical properties at room temperature, such as high flexural strength, excellent oxidation resistance, good corrosion resistance, high wear resistance and low friction coefficient, but also high temperature mechanical properties (strength, creep resistance). Etc.) is the best among known ceramic materials. Hot press sintering, pressureless sintering, hot isostatic pressing, the high temperature strength can be maintained up to 1600 ° C, which is the best material for high temperature strength in ceramic materials. Oxidation resistance is also the best of all non-oxide ceramics. Alias Emery.

Silicon Carbide Ceramics properties:
Silicon carbide ceramics have high hardness, high melting point (2400 ° C), high wear resistance and corrosion resistance, as well as excellent oxidation resistance, high temperature strength, chemical stability, thermal shock resistance, thermal conductivity and good air tightness. And so, it has been widely used in energy, metallurgy, machinery, petroleum, chemical, aviation, aerospace, national defense and other fields.
