High temperature resistant quartz tube, also known as quartz glass tube, is a special industrial skill glass made of silica and is a very excellent foundation material. Quartz glass has a series of excellent physical and chemical functions. As a professional quartz glass tube manufacturer, let me explain the detailed features of quartz glass tubes for you.

1. Has high temperature resistance

The softening point temperature of quartz glass tube is about 1730 ℃, which can be used for a long time at 1100 ℃, and the short-term high operating temperature can reach 1450 ℃.

2. Has corrosion resistance

Except for hydrofluoric acid, quartz glass tubes hardly react chemically with other acid substances. Their acid resistance is 30 times that of ceramics and 150 times that of stainless steel, especially their chemical stability at high temperatures, which is unparalleled by any other engineering data.

3. Good thermal stability

The coefficient of thermal expansion of quartz glass tubes is extremely small, and they can withstand severe temperature changes. When heated to around 1100 ℃, the quartz glass tube will not burst when placed in room temperature water.

4. Good transparency function

Quartz glass tubes have good transmittance throughout the entire spectral range from ultraviolet to infrared, with a visible light transmittance of over 93%, especially in the ultraviolet spectral region, where the Z-large transmittance can reach over 80%.

5. Good electrical insulation function

The resistance value of quartz glass tubes is 10000 times that of ordinary glass, making them excellent electrical insulation materials and possessing outstanding electrical functions even at high temperatures.
