Boron carbide ceramic pressureless sintering process and device
The invention discloses a boron carbide ceramic pressureless sintering process and device. The device comprises a sintering mold, wherein a plurality of inserting pipe assemblies are arranged in the sintering mold, and auxiliary adding assemblies used for injecting and guiding in sintering auxiliaries are arranged on the outer sides of the inserting pipe assemblies. According to the boron carbideceramic pressureless sintering process and device, the inserting pipe assemblies are evenly distributed in the sintering mold, and then through the cooperation effect of the auxiliary adding assemblies, the sintering auxiliaries are injected into injection inner pipes in an equal-layer mode so that the sintering auxiliaries can be evenly distributed on different layer faces, and the sintering auxiliaries are evenly distributed in the sintering mold by adjusting the arrangement positions of the plurality of inserting pipe assemblies; and compared with an existing mode of mixing the sintering auxiliaries with boron carbide particles, the injection of the sintering auxiliaries is controllable, the distribution is more uniform, and the phenomenon that the compactness of parts of the boron carbide particles is different due to the fact that the distribution is not uniform when the auxiliaries are added is avoided.
本发明公开了一种碳化硼陶瓷无压烧结工艺及装置，包括烧结模具，所述烧结模具内安装有多个插管组件，且插管组件外侧设有用于烧结助剂注导入的助剂添加组件，本发明通过插管组件均匀分布在烧结模具内，再通过助剂添加组件的配合作用，实现对注入内管内等层次注入烧结助剂，使烧结助剂能够均匀的分布在不同层次面上，并通过调节多个插管组件的安装位置，实现对烧结助剂均匀的分布在烧结模具内，与现有的烧结助剂与碳化硼颗粒搅拌方式相比，烧结助剂的注入可控，并分布更加均匀，避免了助剂添加时出现分布不均匀现象，导致其各处致密性有所差异。
