Silicon carbide ring-shaped special-shaped parts

Ⅰ.

Product introduction of silicon carbide ring special-shaped parts:

Silicon carbide ring special-shaped parts are non-standardized mechanical parts made of silicon carbide (SiC) as the main material, with complex geometric shapes and special functional designs. This type of product combines the excellent properties of silicon carbide materials. The main features include:

1. High thermal conductivity: The thermal conductivity is as high as 120-150 W/(m·K), which is 3-4 times that of ordinary ceramics.

2. Excellent insulation performance: volume resistivity >10¹⁴Ω·cm, breakdown voltage up to 25-30 kV/mm.

3. High temperature resistance: the working temperature can reach over 1600°C, and the melting point can reach as high as 2700°C.

4. Low thermal expansion‌: The thermal expansion coefficient is only 4.0-4.5×10⁻⁶/K, and the temperature stability is good.

5. High hardness and wear resistance: Vickers hardness HV 2500-2800, annual wear amount <1μm.

6. Chemical stability‌: Resistant to acid and alkali corrosion and oxidation (stable to 1600°C in air).

Application fields

1. New energy power system‌: insulating components of high-voltage arresters and switches; thermal insulation components of energy storage power station inverters.

2.Semiconductor manufacturing: precision components of etching machines and photolithography machines; corrosion-resistant components in wafer processing.

3. Aerospace and national defense: missile fairings, satellite reflectors; rocket engine high temperature resistant parts.

4. Industrial wear-resistant parts‌: sealing rings and bearings for chemical pumps; steel rolling molds and wear-resistant liners.

5. Medical equipment‌: high-temperature resistant components of sterilization equipment such as high-frequency electrosurgers.
