1. Ultra-High Purity – Zero-Contamination Temperature Measurement

SiO₂ purity ≥ 99.99%, premium grades up to 99.999%
No devitrification, volatilization or particle shedding at high temperatures
Never introduces metal contamination into the furnace atmosphere
A key safeguard for semiconductor wafer yield — impurity contamination can scrap an entire wafer batch

2. Extreme Heat Resistance for Demanding Processes

Long-term service temperature 1100°C – 1200°C, short-term up to 1450°C
Softening point approx. 1700°C, far higher than ordinary glass and metal sheaths
Structurally stable at high temperatures — no softening or deformation
Compatible with diffusion, oxidation, annealing, CVD and other high-temperature processes

3. Fast Thermal Response – Accurate, Stable Measurement

Thin wall, high density and good thermal conductivity
Fast thermal response with timely temperature signal transmission
Low porosity, minimal signal drift, stable measurement accuracy over long-term use
Provides a reliable basis for closed-loop process temperature control

4. Strong Corrosion Resistance – Superior Chemical Inertness

Resists strong acids (except hydrofluoric acid), weak alkalis and most corrosive atmospheres
No reaction with halogens, chlorine, oxygen or other process gases at high temperatures
Effectively resists erosion by furnace gases, dust and molten materials
Service life far exceeds stainless steel and ceramic sheaths

5. Thermal Shock Resistant – No Cracking Under Rapid Temperature Changes

Ultra-low thermal expansion coefficient (5.5×10⁻⁷/°C)
No cracking or fracturing under sudden temperature changes
Suitable for batch processes with frequent heating and cooling cycles

6. High Electrical Insulation – Electrical Safety

Excellent high-temperature electrical insulation
Eliminates leakage interference between thermocouple wires and from wires to the furnace body
Ensures clean, safe and reliable measurement signals

7. Complete Specifications – Deep Customization

Structures: closed-end tube (one end sealed, standard), open tube, two-bore tube
Outer diameter: φ2mm – φ50mm (selected per thermocouple specification)
Wall thickness: 0.5mm – 5mm customizable
Length: customizable up to 3 meters or more
Processing: flame-polished sealed ends, flanging, flange fitting, diameter reduction, frosting
Compatibility: fits K, S, R, B and other thermocouple types
