What is the operating temperature of a quartz tube? (4 Key Points)

The operating temperature of a quartz tube is up to 1200°C, with a softening point at 1270°C.

However, continuous use at 1200°C should not exceed three hours to prevent damage.

1. Operating Temperature

What is the operating temperature of a quartz tube? (4 Key Points)

Quartz tubes are designed to withstand high temperatures, making them suitable for various high-temperature applications such as in tube furnaces used for semiconductors, batteries, and other materials testing.

The maximum recommended operating temperature for these tubes is 1200°C.

This temperature range is crucial for processes that require precise heating and cooling cycles, such as vacuum brazing, heat treatment, and sintering.

2. Softening Point and Duration of Use

The softening point of a quartz tube is 1270°C.

This is the temperature at which the material begins to lose its structural integrity and becomes less resistant to thermal stress.

To prevent reaching this point during operation, it is advised that the quartz tubes should not be used for more than three hours at 1200°C.

This limitation helps in maintaining the durability and effectiveness of the quartz tube over time, preventing premature failure due to excessive heat.

3. Thermal Shock Resistance

Quartz tubes are known for their excellent thermal shock resistance, which allows them to withstand rapid temperature changes from 1000°C to room temperature without cracking or breaking.

This property is due to their low coefficient of thermal expansion, which means they expand and contract minimally with temperature changes.

This makes them ideal for applications where sudden temperature fluctuations are common.

4. Material Considerations

Quartz tubes are made from either natural or synthetic quartz sand, which contributes to their high thermal and electrical resistance.

The transparency of the quartz tube is also beneficial for applications where visual monitoring of the process is necessary.

However, it is important to note that while quartz tubes are cost-effective and transparent, they may not withstand as many heat-cool cycles as other materials, which is a consideration for long-term or high-frequency use.

In summary, while quartz tubes can operate at temperatures up to 1200°C, careful consideration of the duration of use and the thermal conditions is necessary to ensure their longevity and effectiveness.
