Choosing a high-temperature tube furnace, the furnace tube is the core component that directly determines the upper limit of equipment temperature resistance, atmosphere adaptability, experimental stability, and service life. Many university laboratories and users of new material research and development are torn between choosing quartz tubes or corundum tubes for tube furnace tubes? There is no absolute superiority or inferiority between the two, the core depends on the process temperature, atmosphere type, material system, and experimental requirements. Below, we will compare the differences between the two in detail and provide a clear selection idea for everyone....

The nitrogen vacuum sintering furnace adopts a vacuum degreasing+high-purity nitrogen protection sintering process, mainly used for high-temperature sintering of powder metallurgy, advanced ceramics, and magnetic materials to prevent workpiece oxidation, improve material density, support laboratory research and development and industrial mass production, and the equipment can be customized according to non-standard requirements....

The low vacuum atmosphere furnace can complete the sintering, annealing, and reduction heat treatment of new materials. First, a low vacuum is drawn and then a protective atmosphere is introduced to effectively prevent high-temperature oxidation of materials. It is widely used in advanced ceramics, new energy powders, powder metallurgy, and university research experiments. The equipment supports non-standard customization....

In the field of advanced new materials, high-temperature heat treatment of ceramics and carbon materials has high environmental requirements, and oxidation is prone to occur at high temperatures. Ordinary resistance furnaces cannot meet the requirements of oxygen free ultra-high temperature processing. The graphite vacuum furnace uses high-purity graphite as the heating element and thermal insulation field, and can achieve ultra-high temperature heating of 1700-2200 ℃ under vacuum or inert protective atmosphere conditions. It is the core heat treatment equipment for ceramic sintering, carbon material graphitization, annealing and degassing....
