Overview of Quartz Ceramic
Quartz ceramic, also known as fused silica ceramic, is a high-performance technical ceramic composed primarily of silicon dioxide (SiO₂) in a non-crystalline state. It is manufactured by fusion and controlled cooling of high-purity silica, resulting in a material that combines the best properties of glass and traditional ceramics. Our quartz ceramic products are engineered to deliver exceptional stability, purity, and performance in the most demanding industrial applications.
Features of Quartz Ceramic
- Extreme Thermal Shock Resistance: Due to its extremely low coefficient of thermal expansion (CTE), quartz ceramic can withstand rapid temperature changes without cracking.
- Low Thermal Conductivity: Acts as an excellent thermal insulator, protecting surrounding components from high heat.
- High Chemical Purity: Typically >99.9% SiO₂, making it inert to most acids and resistant to corrosion.
- Dielectric Strength: Excellent electrical insulator even at high temperatures and high frequencies.
- High Refractoriness: Retains its shape and strength at continuous operating temperatures up to 1100°C.

5 FAQs of Quartz Ceramic
1. What is the difference between quartz ceramic and ordinary glass?
Quartz ceramic (fused silica) is engineered for industrial use. Unlike ordinary glass, it contains no additives, has a much higher service temperature, and can withstand rapid heating and cooling (thermal shock) that would shatter standard glass.
2. Can quartz ceramic be machined into complex shapes?
Yes. While it can be formed in molds, our quartz ceramic components are often supplied in a semi-sintered state for machining. We offer precision grinding and cutting services to achieve tight tolerances and complex geometries.
3. Is this material safe for use with food or pharmaceuticals?
Yes. Due to its high chemical purity and inertness, quartz ceramic does not react with or contaminate products, making it suitable for pharmaceutical processing equipment and high-purity food manufacturing.
4. What is the maximum operating temperature?
For continuous use, our standard quartz ceramic products are rated up to 1100°C. For short-term exposure or specific applications, please consult our engineering team to verify the material limits.
5. How does the porosity affect its use in liquids?
Standard quartz ceramic has a slight porosity. However, for liquid containment or vacuum environments, we offer glazed or fully dense variants that create a non-porous, vacuum-tight surface.
