Advantages Of Silicon Carbide Ceramic Sheath

Silicon carbide ceramic sheath uses SIC materials with excellent mechanical properties, excellent oxidation resistance, high wear resistance and low friction coefficient, so that it can be used in extremely harsh environments, or to extend the service life of parts.

Silicon Carbide Ceramic Sheath Applications

Generally, SIC ceramic sheath is used because of its ultra-high hardness, oxidation resistance and high temperature resistance. In some applications that are very easy to wear and have high service temperature, the use of SIC sheath as a component can effectively extend the service life, so it has great economic benefits.

In addition, due to the superior performance of the parts made of silicon carbide, they have been widely used in petroleum, chemical industry, microelectronics, automobile, aerospace, aviation, paper making, laser, mining, atomic energy and other industrial fields.

Now, silicon carbide has been widely used in the fields of high-temperature bearings, bulletproof plates, nozzles, high-temperature corrosion resistant parts and electronic equipment components in the high-temperature and high-frequency range.

Silicon Carbide Ceramic Sheath Performance

SiC ceramic sheath prepared by direct sintering has the characteristics of high hardness, corrosion resistance, oxidation resistance and low friction coefficient. In addition, the greatest feature of silicon carbide ceramics is that they can still maintain high mechanical strength at high temperatures. The strength of ordinary ceramic materials will be significantly reduced at 1200~1400 ℃, while the bending strength of silicon carbide will remain at a higher level at 1400 ℃.

The basic characteristics of directly sintered silicon carbide ceramics are as follows:

• Colour: Dark Gray
• Density: 3.15g/cm³
• Porosity: ≤0.1%
• Hardness: 22GPa
• Compressive Strength: 2600MPa
• Flexural Strength: 400MPa
• Elastic Modulus: 410GPa
• Maximum Use Temperature: 1400℃
• Thermal Conductivity: 100~120W/(m・K)
• Coefficient Of Thermal Expansion: 4 x 10^-6/°C
