Quartz tubes, particularly the transparent type, can withstand temperatures up to 1100 degrees Celsius.
However, their softening point is at 1270 degrees Celsius.
It is recommended not to use them for more than three hours at 1200 degrees Celsius.
Transparent quartz tubes are highly resistant to thermal shock.
They can withstand a temperature drop from 1000 degrees Celsius to room temperature.
This resilience is due to their extremely low coefficient of thermal expansion.
They also have excellent electrical strength, providing stability under temperature variations.
The softening point of a quartz tube is 1270 degrees Celsius.
This is the temperature at which the material begins to soften and lose its structural integrity.
When operating at 1200 degrees Celsius, it is crucial to limit usage to no more than three hours to prevent damage.
Quartz tubes are commonly used in horizontal split tube furnaces.
These furnaces are designed for maximum temperatures ranging from 1200°C to 1700°C.
They are equipped with programmable temperature controllers for precise heating and cooling rates.
This enhances the efficiency and safety of operations involving high temperatures.
Fused quartz tubes are made from high-purity quartz crystals melted at 2000°C.
They offer superior optical and thermal properties compared to other types of glass.
This high-temperature process ensures the material's purity and enhances its performance in high-temperature environments.
In summary, the transparent quartz tube is designed to handle extreme temperatures.
Its working range is up to 1100 degrees Celsius, with a softening point of 1270 degrees Celsius.
Its ability to withstand thermal shock and maintain structural integrity at high temperatures makes it a valuable component in various high-temperature applications.
