During the coating process, the quartz tube can be heated to achieve the effect of annealing. During annealing, the material structure is tighter and a better coating effect is achieved.
The quartz tube has the following characteristics:
- Heat resistant： The softening temperature of the quartz tube is about
- Corrosion resistance：Quartz hardly has chemical reactions with many acids except hydrofluoric acid. Its great chemical stability at high temperatures is unmatched by any other engineering material.
- Great electrical insulation：Quartz is a great electrical insulating material with good insulation properties even at high temperatures.
