Factory made high temperature resistant 1200 corrosion resistant large diameter quartz tubes for furnace

Performance & Applications of Large-Diameter Quartz Tubes

Core Performance

Large-diameter quartz tubes are high-purity fused silica products (SiO₂ ≥99.99%) with exceptional material characteristics, ideal for harsh industrial and scientific environments.

1. Extreme High-Temperature Resistance
Continuous service temperature up to 1100°C, short-term peak resistance 1450°C, and a softening point of 1730°C, ensuring structural stability under thermal stress.

2. Superior Thermal Shock Resistance
Ultra-low thermal expansion coefficient (5.5×10⁻⁷/°C), enabling it to withstand rapid temperature cycles without cracking.

3. Exceptional Chemical Inertness
Resistant to strong acids, alkalis, and organic solvents (except hydrofluoric acid). Its chemical stability is far superior to ceramics and stainless steel, making it suitable for corrosive media handling.

4. Optical Clarity & Transmissivity
Light transmittance exceeds 90% across UV to infrared spectra, meeting strict optical-grade application requirements.

5. Outstanding Electrical Insulation
High resistivity (10¹⁸ Ω·cm at 20°C), providing reliable insulation for high-voltage and high-frequency scenarios.

6. High Mechanical Strength
Compressive strength up to 1150 N/mm², ensuring durability under pressure in industrial systems.

Leveraging its comprehensive performance, large-diameter quartz tubes are widely used in core industries and cutting-edge fields:

1. Semiconductor & Photovoltaic
Critical components for diffusion furnaces, oxidation tubes, and CVD systems; essential for high-purity thermal processes in wafer and solar cell manufacturing.

2. Industrial Heating & Furnace Systems
Muffle furnace liners, heater protection sleeves, and high-temperature reaction vessels, widely applied in chemical, food, and pharmaceutical processing.

3. Chemical & Environmental Engineering
Corrosion-resistant pipelines for transporting strong acids (e.g., concentrated sulfuric acid) and high-purity media; service life is 5x longer than PTFE tubes in harsh conditions.

4. Optics & Laser Technology
Casings for high-power lasers, optical instrument components, and UV light sources, thanks to its excellent light transmittance and thermal stability.

5. Scientific Research & Medical Equipment
High-temperature reaction kettles, sample observation cells, and medical device components, providing a contamination-free environment for experiments and clinical applications.

6. Aerospace & Advanced Manufacturing
High-temperature insulation components and precision sensor housings, meeting the stringent reliability requirements of aerospace and high-end manufacturing.
