Beryllium oxide ceramic structural member sintering method
The invention discloses a beryllium oxide ceramic structural part sintering method in the technical field of ceramic processing, which comprises the following steps: S1, selecting sagger kiln furniture which adapts to the size of a product green body and has a flat bottom, and paving a layer of ceramic balls at the bottom of the sagger kiln furniture; s2, a green gasket is arranged at the upper end of the ceramic ball, the size of the green gasket is matched with that of the product green, and the shrinkage coefficient is the same as that of the product green; s3, arranging a layer of isolation powder at the upper end of the green gasket; s4, the product green body is placed at the upper end of the isolation powder, and a sintered whole is formed; s5, the sintered whole is moved into a sintering furnace to be sintered; according to the method, the large beryllium oxide structural member can be obtained, and compared with a traditional sintering method, the sintering success rate is greatly increased, and the deformation and cracking risks in the product sintering process are greatly reduced.
本发明公开的是陶瓷加工技术领域的氧化铍陶瓷结构件烧结方法，包括以下步骤：S1:选取适应产品生坯尺寸且底部平整的匣钵窑具，在上述匣钵窑具底部铺设一层陶瓷球；S2:在陶瓷球上端设置生坯垫片，上述生坯垫片尺寸与产品生坯尺寸相适应且收缩系数与产品生坯相同；S3:在上述生坯垫片上端设置一层隔离粉；S4:将产品生坯放置在隔离粉上端，形成烧结整体；S5:将烧结整体移至烧结炉内进行烧结；在该方法下，可以获得大型氧化铍结构件，相对于传统烧结方法，大大提高了烧成成功率，使产品烧成过程中的变形、开裂风险极大的下降。
