Description

Technical Field

[0001] The utility model belongs to the technical field of ceramic sintering equipment, and particularly relates to an equipment structure with debinding and vacuum atmosphere sintering functions. Background Art

[0002] Among advanced ceramic preparation technologies, the gel-casting process can produce green bodies with good uniformity, high density and high strength. This process mainly prepares a slurry with low viscosity and high solid volume fraction. Under the action of initiators and cross-linking agents, monomers undergo polymerization reactions to form a three-dimensional network structure with a certain strength. The suspended particles are then fixed in situ into a specific size and shape, completing the preparation of the green body. Before sintering, it is necessary to remove organic matter such as cross-linking agents inside the green body. Therefore, the green body prepared by the gel-casting process needs to be debinded. After debinding, large-sized green bodies will have a large amount of organic matter volatilized, and the internal structure has many pores. During transportation, defects are very likely to occur. In order to reduce the defects of large-sized ceramic green bodies during transportation after debinding, high-temperature sintering is required to make the green body shrink to a certain extent, thereby increasing the strength of the green body.

[0003] However, the heating elements and insulation layers of existing debinding furnaces are only suitable for air atmospheres, while oxynitride ceramics will oxidize in air atmospheres above 1000°C. Therefore, there is an urgent need to develop a sintering furnace that can meet the requirements of both air debinding and vacuum operation to solve the debinding and transfer issues of large-scale oxynitride ceramics.
