High-Purity Quartz Tubes Usage & Safety Tips in Furnaces

High-Purity Quartz Tubes: Usage & Safety Tips in Furnaces

Quartz tubes start softening when exposed to temperatures above 1265°C. For safety and optimal performance, it’s recommended not to exceed a furnace temperature of 1210°C for more than three hours. The temperature resistance of quartz tubes is directly related to their purity—the higher the purity, the better the heat resistance. Key Recommendations for Using Quartz Tubes in Tube Furnaces At GlobalQT, we specialize in high-quality quartz tubes and heating elements.

高温における水晶管の安定性に影響する要因

高温における水晶管の安定性に影響する要因

Quartz tubes (primarily composed of silicon dioxide, SiO2) exhibit chemical stability at high temperatures, which is influenced by several key factors. The primary factors include: 1. Temperature As the temperature increases, the chemical stability of quartz tubes remains generally constant. At high temperatures (above 1100°C), quartz tubes may undergo structural changes such as lattice distortion or phase transitions. However, quartz tubes can typically withstand temperatures as high as 1400°C without significant chemical reactions. For this reason, quartz tubes are commonly used in industrial applications involving extreme temperatures, such as semiconductor manufacturing or high-temperature chemical reactions. 2. Atmosphere The stability of quartz tubes varies depending on the chemical atmosphere. In pure
