Effect of nano - al2o3 powder additive on sintering behaviors of alumina ceramics
纳米晶添加氧化铝粉体的低温烧结研究
The thermal shock resistance of the prepared material is explored too . processing parameters were comprehensively investigated to achieve better mechanical strength and microstructure , experimental results indicate that suitable amount of sintering aids can promote the development of sian siaona ) and increase the crystal size , while excessive sintering aids amount will exert a side effect ; biding phase increases obviously with si powder additive which greatly improve the strength of the composite
本论文着重探讨了在利用该方法制备si _ 3n _ 4 ( si _ 2on _ 2 ) - sic复合材料过程中的烧结助剂引入量、 si粉加入量、 sic颗粒级配和氮化制度对复合材料基体相生成的影响及对复合材料强度的影响，同时也初步探讨了si _ 3n _ 4 ( si _ 2on _ 2 ) - sic复合材料的抗热震性能。
