Chemical And Thermal Resistant Ceramic For High-Temperature Applications Exceptional Stability

Silicon oxide ceramic (SiO₂ ceramic) is a high-performance ceramic material with exceptional stability, manufactured using high-purity silicon dioxide (SiO₂≥99.7%) through specialized sintering processes. This product demonstrates unparalleled chemical and thermal stability in extreme environments, making it an ideal choice for demanding industrial applications.

Primary Applications

• Semiconductor manufacturing: Corrosion-resistant components for wafer processing equipment

• Optical industry: Substrate material for high-precision optical lenses

• Chemical processing: Corrosion-resistant elements for strong acid/alkali environments

• High-temperature applications: Components for heat treatment equipment below 1600°C

• Electronics: High-frequency insulation components

Stability Advantages

✓ Superior chemical inertness: Resistant to all inorganic acids (except HF) and organic solvents
✓ Excellent thermal stability: CTE only 0.5×10⁻⁶/°C (20-1000°C)
✓ Low dielectric loss: Dielectric constant 3.8 at 1MHz, loss tangent 0.0002
✓ Thermal shock resistance: Withstands rapid quenching from 1000°C to room temperature
✓ Long-term stability: Service life exceeding 10 years in harsh environments
