Quartz tubes look very similar to ordinary glass tubes on the surface, but in fact, they have essential differences in composition. Quartz tubes also have much stronger performance than glass tubes. Today, the editor of Hoinfrared will take you to understand the differences between quartz tubes and glass tubes.

1. Melting point difference. Quartz tubes are crystals, while glass tubes are non-crystals.

2. Different main components. The main component of quartz tubes is silicon dioxide, while that of glass tubes is sodium silicate, silicon dioxide and calcium silicate.

3. Different silicon dioxide content. Quartz tubes are made by melting pure silicon dioxide, with a content of over 99%. The silicon dioxide content of glass tubes is generally between 70% and 80%, and other components include sodium oxide, calcium oxide, lead and other alkali metals or alkaline earth metals. Such a composition is to lower the melting temperature and improve the quality of the glass.

4. Different chemical structures. Whether natural or artificial, the molecular structure in glass tubes is random, while quartz tubes have symmetrical molecular structures.

5. Different tolerance to temperature and pressure. Although both are formed deep in the earth's crust, quartz tubes can withstand higher temperatures and can be used for a long time at temperatures up to 1100℃. Even if the surrounding temperature reaches 1450℃ for a short time, it will not affect them. Moreover, because quartz tubes are more resistant to high pressure, they can be used as protective layers and thus can be used as substitutes for glass in high-temperature harsh environments.

6. Huge difference in corrosion resistance. Scientific data shows that, except for hydrofluoric acid, other acids have almost no effect on quartz tubes, while glass tubes do not have such resistance.

7. Different roles in industrial trade. Glass tubes are excellent electrical insulators, while quartz tubes have strong conductivity. Therefore, glass tubes and quartz tubes can be used respectively to guide or cut off current.
