What are the temperatures of vacuum tube furnaces?

The temperature range of vacuum tube furnaces usually varies depending on the specific model of the furnace, heating elements, and the material and quality of the pipes. Generally speaking, the operating temperature range of vacuum tube furnaces is between 500 ° C (932 ° F) and 1600 ° C (2912 ° F).

Specifically, the temperature range of a vacuum tube furnace can be subdivided into the following parts:
Low temperature range:
Usually refers to the temperature range of 500 ° C to 1000 ° C (932 ° F to 1832 ° F). This temperature range is suitable for some experiments or processes that require lower temperature heating.

Medium temperature range:
Usually between 1000 ° C and 1600 ° C (1832 ° F to 2912 ° F). This temperature range is applicable to most common experiments and processes, such as ceramic sintering, metal heat treatment, etc.

High temperature range:
Exceeding the temperature range of 1600 ° C until reaching the maximum temperature limit of the vacuum tube furnace. Within this temperature range, some high-temperature experiments or the preparation of special materials can be carried out.
The temperature range may vary for different models and configurations of vacuum tube furnaces. For example, the operating temperature range of the AS-1400GSL series tube furnace is 800 ℃ to 1600 ℃, while GR The maximum temperature of the TF series vacuum tube furnace can reach 1400 ℃.
In addition, the temperature range of vacuum tube furnaces is also limited by the material of the pipes and the heating method. For example, the commonly used quartz tube has a temperature limit of 1200 ℃ to 1500 ℃, while stainless steel tubes have a smaller temperature range of approximately 800 ℃ to 1000 ℃. Therefore, when selecting pipes and heating methods, it is necessary to comprehensively consider the needs of experiments or processes.

In summary, vacuum tube furnaces have a wide temperature range and can be selected according to specific needs. When selecting and using a vacuum tube furnace, it is necessary to carefully read the equipment manual, understand its temperature range, heating method, pipe material and other relevant information, to ensure the accuracy and safety of the experiment.
