The powder was pressed through molding and cold isostatic pressure , which increased the density and decreased the uneven distribution of stress inside the briquet to make the ceramic briquet equally compact 粉料采取模壓和冷等靜壓相結合的方法壓制,增大了坯體內部的密度并減少了應力的分布不均,得到均勻致密的陶瓷坯體。
The microstructure of the polycrystal remains to be optimized to achieve good performance . to reduce the high cost and high - energy expedition of melting method , a solvothermal process followed by a sintering procedure of compacted pellets produced by using cold isostatic pressure method were mentioned to prepare polycrystalline samples of the ternary ( snte ) x ( bi2te3 ) y compounds 為彌補熔煉法高成本,高能耗等諸多缺陷,本文還采用溶劑熱法,成功合成了bi _ 2te _ 3和三元( snte ) _ x ( bi _ 2te _ 3 ) _ y化合物,并采用冷等靜壓成型,結合常壓燒結的方法制備塊體樣品。
