Overview of Quartz Ceramic
Quartz Ceramic, also known as fused quartz or silica ceramic, is a high-performance material engineered for extreme environments. Unlike traditional ceramics, it is composed of vitreous (non-crystalline) silica, resulting in a unique combination of thermal, electrical, and chemical properties. This material is specifically designed to offer exceptional thermal shock resistance, maintaining structural integrity where other materials would fail. It is the premier choice for applications demanding purity, stability, and resilience under thermal stress.
Features of Quartz Ceramic
- Unmatched Thermal Shock Resistance: With an extremely low coefficient of thermal expansion, quartz ceramic can withstand rapid temperature changes from over 1000°C to room temperature without cracking.
- High-Temperature Stability: It maintains excellent mechanical strength and dimensional stability at temperatures up to 1100°C.
- Superior Electrical Insulation: Offers high dielectric strength and low electrical conductivity, making it an ideal insulator in high-temperature and high-frequency applications.
- Exceptional Chemical Purity & Resistance: Highly inert and resistant to most acids, salts, and corrosive atmospheres, ensuring process purity and long service life.
- Low Thermal Conductivity: Acts as an effective thermal insulator, protecting sensitive components from heat.
- High Visible & IR Transmittance: Certain grades are engineered for optical applications, transmitting visible and infrared light.
Applications of Quartz Ceramic
Quartz Ceramic is indispensable across a wide range of high-tech industries:
- Semiconductor & Solar: Wafer boats, diffusion furnace tubes, crucibles for silicon crystal growth, and PV cell processing.
- Metallurgy & Foundry: Rad tubes for temperature sensors, risers, and investment casting cores.
- Lighting: Envelopes and components for high-intensity discharge (HID) lamps.
- Aerospace & Defense: Radomes, missile nose cones, and thermal insulation substrates.
- Laboratory & Chemical Processing: Crucibles, trays, and linings for high-purity chemical reactions.

5 FAQs of Quartz Ceramic
1. How does Quartz Ceramic differ from traditional Alumina Ceramic?
While both are technical ceramics, Quartz Ceramic is non-crystalline (amorphous) and has a much lower thermal expansion coefficient, giving it far superior thermal shock resistance. Alumina is polycrystalline, generally harder, and has higher mechanical strength at room temperature.
2. Can Quartz Ceramic be machined to custom shapes?
Yes. It can be precision machined in its fired state using diamond tools to create complex geometries, tight tolerances, and custom components for specific applications.
3. What is the maximum continuous operating temperature?
The recommended maximum continuous use temperature in an oxidizing atmosphere is 1100°C. For short-term exposure, it can withstand up to 1300°C.
4. Is Quartz Ceramic resistant to hydrofluoric acid (HF) and strong alkalis?
No. Like all silica-based materials, it is severely attacked by hydrofluoric acid and strong caustic solutions (e.g., sodium hydroxide). It is highly resistant to most other acids.
5. Why is it used in semiconductor manufacturing?
Its exceptional purity prevents wafer contamination, its thermal stability ensures process consistency, and its resistance to thermal shock is critical for rapid heating and cooling cycles in diffusion furnaces.
