What is the typical temperature for a muffle furnace during heat treatment?

The temperature range of the heat treatment muffle furnace varies depending on its design and application requirements. Generally speaking, the temperature range of a muffle furnace can range from several hundred degrees Celsius to several thousand degrees Celsius. The following is a summary of the common temperature range for heat treatment muffle furnaces:

Low temperature section:
In the range of 100 ° C to 500 ° C, the muffle furnace is suitable for some low-temperature heat treatments and tests, such as preheating, drying, or low-temperature sintering of certain materials.
Medium temperature range:
The muffle furnace is widely used in most materials science and chemical experiments within the range of 500 ° C to 1500 ° C (some sources mention 900 ° C to 1300 ° C or wider). This temperature range is suitable for material thermal stability testing, phase transition research, catalyst preparation, and performance testing.
High temperature section:
At temperatures above 1500 ° C (some special models may reach or exceed 3000 ° C), the muffle furnace is suitable for high-temperature experiments such as material melting, graphitization, and high-temperature sintering. These high-temperature treatment processes are of great significance for optimizing material properties and developing new materials.
The temperature range varies for different types of muffle furnaces

Conventional muffle furnace: typically designed for temperatures between 900 ° C and 1800 ° C, capable of meeting the needs of most heat treatment experiments.
High temperature muffle furnace: Some special models of high-temperature muffle furnaces have a higher temperature range, such as those used for special material heat treatment in nuclear industry, aerospace and other fields.
In addition, the heating elements of the muffle furnace can also affect its temperature range. For example, resistance wire heating elements are typically used in equipment below 1300 ° C, while the heating temperature range for silicon carbon rod muffle furnaces is between 1300 ° C and 1400 ° C, and for silicon molybdenum rod muffle furnaces it is between 1400 ° C and 1700 ° C (or higher).

In summary, the temperature range of the heat treatment muffle furnace varies depending on its type, configuration, and application requirements. When choosing a muffle furnace, the required temperature range should be determined based on specific experimental or industrial requirements, and factors such as the performance characteristics, heating rate, and temperature control accuracy of the muffle furnace should be considered.
