What is the temperature for sintering in a vacuum muffle furnace?

The vacuum muffle furnace has a wide temperature range for sintering, usually between 500 ℃ and 1800 ℃. The specific sintering temperature depends on various factors, let’s analyze it in detail below!

Material characteristics: The sintering temperature of different materials varies. For example, the sintering temperature of ordinary ceramic materials is generally between 1000 ℃ and 1400 ℃; Some high-performance ceramics, such as silicon carbide and boron nitride, may require high temperatures of 1600 ℃ -1800 ℃ to achieve good sintering results. The sintering temperature of metal powder is relatively low, and the sintering temperature of common iron-based and copper based powders is generally between 500 ℃ and 1000 ℃.
Sintering purpose: If it is for preliminary molding and impurity removal, lower temperatures may be used, such as 500 ℃ -800 ℃; To achieve densification of materials and improve their mechanical and physical properties, higher temperatures may be required, possibly above 1000 ℃.
Process requirements: Some special sintering processes, such as rapid sintering, hot pressing sintering, etc., also have different temperature requirements. Rapid sintering may require reaching higher temperatures in a short period of time, while hot pressing sintering requires a combination of pressure and temperature, typically around 1000 ℃ -1600 ℃.
