High Purity Tranparent Quartz Glass Boat

1. High temperature resistant: Quartz glass tube softening point temperature of about 1730 degrees Celsius, can be used for a long time at the temperature of 1100 degrees Celsius, the highest temperature in a short time up to 1450 degrees Celsius.

2.Corrosion: Except hydrofluoric acid, quartz glass and other acids almost no chemical reaction, the ceramic acid resistance is 30 times, 150 times of  stainless steel, especially the chemical stability at high temperatures, any other engineering materials are incomparable. 

3.Good thermal stability: The thermal expansion coefficient of the quartz glass tube is very small, which can withstand the severe temperature change, heating the quartz to1100c, it will not burst put into room temperature water.

4.Good light transmittance: The quartz glass has good transmittance in the ultraviolet and infrared spectral bands, the transmittance of visible light is above 93%, especially in the ultraviolet spectral region. The maximum transmittance is above 80%.

5.Good electrical insulation: The resistance value of quartz glass tube is equivalent to ten thousand times that of ordinary glass, and it is an excellent electrical insulating material.
