The selection of the lamp material of the infrared heating tube is not arbitrary. Special materials with strong infrared transmittance must be used. This material can work continuously and stably above 1000°C and has good corrosion resistance.

The advantages of quartz lamps:

1. High mechanical strength and toughness;

2. Chemical stability;

3. High power density;

4. Convenient wiring method;

5.The length can be up to 3.5 meters.
