What Are The Differences And Common Points between Vacuum Sintering Furnace And Atmosphere Sintering Furnace?

Vacuum sintering furnace and atmosphere sintering furnace are two common sintering equipment, their working environment and characteristics in the sintering process have some differences and common points.

1. Working environment: vacuum sintering furnace adopts a vacuum environment in the sintering process, that is, gas is removed at high temperature, so that the sintering process is carried out in a gas-free environment. The atmosphere sintering furnace regulates the atmosphere in the sintering process by controlling the atmosphere composition, such as nitrogen, hydrogen, etc. 2. Sintering effect: vacuum sintering furnace can provide a highly pure sintering environment, avoid the presence of oxidation reaction and impurities, and can obtain high purity sintered products. The atmosphere sintering furnace can achieve different sintering effects by adjusting the atmosphere composition, such as controlling oxygen partial pressure, atmosphere pressure, etc., to achieve specific sintering requirements. 3. Equipment structure: vacuum sintering furnace needs to have good sealing performance and vacuum degree control system to maintain a stable vacuum environment. The atmosphere sintering furnace needs to have the atmosphere control system and the gas supply system to achieve the precise control of the atmosphere composition.

1. Sintering principle: vacuum sintering furnaces and atmosphere sintering furnaces are heat treated at high temperatures to combine powder particles into dense materials, thereby improving the density and performance of materials. 2. Application: vacuum sintering furnace and atmosphere sintering furnace are widely used in metal, ceramics, composite materials and other fields, for the preparation of high-performance materials and parts. 3. Sintering temperature: vacuum sintering furnace and atmosphere sintering furnace can provide a high temperature environment to meet the sintering temperature requirements of different materials.

It should be noted that the choice of vacuum sintering furnace or atmosphere sintering furnace depends on the specific material and sintering requirements, as well as the availability and cost of equipment and other factors.
