Description

Technical Field

[0001] The utility model belongs to the technical field of ceramic sintering, and in particular relates to a ceramic product sintering device. Background Art

[0002] There are various methods for sintering ceramics. Microwave sintering, unlike traditional heating methods, involves electromagnetic waves penetrating the medium and heating it. This energy is converted into molecular kinetic energy, which is then converted into thermal energy within the material. The heat generated within the material, combined with the vibrations induced by high-frequency microwaves, effectively raises the sintering temperature. However, due to the many factors that influence high-temperature microwave sintering, microwave sintering of the sample is often required. During this process, the sample must be wrapped in insulation to facilitate sintering.

[0003] To achieve high density during cold pressing of the green body, a certain amount of PVC is added to the original powder. However, PVC evaporates at high temperatures and forms fumes, which tend to float in the furnace. During sintering, the fumes in the furnace tend to adhere to the surface of the ceramic product, affecting its production quality. Utility Model Content
