How Are Special-Shaped Quartz Tubes Formed?

Special-shaped quartz tubes are custom-manufactured strictly according to user requirements through processes including cutting, firing, sealing, bending, grinding, and specialized forming techniques. Our company specializes in producing both straight quartz tubes and various special-shaped tubes including "O"-type, "C"-type, "U"-type, spiral, and other specifications.

Custom Manufacturing Capabilities:

We can produce special-shaped quartz tubes to meet specific customer demands, including:

• Geometric shapes: U-shaped, C-shaped, Ω-shaped, corrugated, S-shaped, pear-shaped, and spiral tubes

• Processing techniques: Cutting, fire-polishing, bottom sealing, forming, bending, grinding, and surface patterning

• Instrument fabrication: Custom quartz glass apparatuses of various designs

Exceptional Material Properties:

Quartz glass demonstrates superior performance characteristics:

1. Thermal Properties

   • Softening point: 1730°C

   • Long-term service: ≤1200°C

   • Short-term tolerance: Up to 1450°C

2. Chemical Resistance

   • Nearly inert to all acids except hydrofluoric acid

   • Acid corrosion resistance:
     ×30 better than ceramics
     ×150 better than stainless steel

   • Unparalleled high-temperature chemical stability among engineering materials

3. Thermal Shock Resistance

   • Extremely low thermal expansion coefficient

   • Can withstand rapid temperature changes (e.g., heating to 1100°C then immersion in room-temperature water without cracking)

4. Optical Performance

   • Excellent full-spectrum transmission (UV to IR)

   • Visible light transmittance: >93%

   • UV range transmittance: >80%

5. Electrical Properties

   • Resistivity: 10,000× higher than conventional glass

   • Maintains superior insulation even at elevated temperatures

Industrial Applications:

These outstanding physicochemical properties enable wide applications across:
Electric lighting sources
Semiconductor manufacturing
Optical communications
Military/defense systems
Metallurgy & building materials
Chemical processing
Mechanical/Power/Environmental sectors
