Sintering method of gadolinium oxysulfide scintillation ceramic, gadolinium oxysulfide scintillation ceramic and application
The invention discloses a sintering method of gadolinium oxysulfide scintillation ceramic, the gadolinium oxysulfide scintillation ceramic and application. According to the method, the gadolinium oxysulfide raw material cake obtained through dry pressing is sintered under the positive pressure condition to obtain the gadolinium oxysulfide scintillation ceramic, in the sintering process, the gadolinium oxysulfide raw material cake is subjected to the positive pressure and the high temperature at the same time, the pressure comes from mixed gas, gadolinium oxysulfide can be pressed in all directions, meanwhile, the powder is in a thermoplastic state, and the gadolinium oxysulfide scintillation ceramic is obtained. And contact diffusion of particles, proceeding of a flowing mass transfer process and gas discharge are facilitated. Therefore, the sintering temperature can be reduced, the sintering time can be shortened, grain growth and exhaust of gas between grains or particles can be inhibited, ceramic products with fine grains and high density can be obtained, and meanwhile, the mechanical property of the ceramic material can be improved.
本发明公开了硫氧化钆闪烁陶瓷的烧结方法、硫氧化钆闪烁陶瓷及应用。本发明中，干压得到的硫氧化钆原料饼料在正压条件下烧结得到硫氧化钆闪烁陶瓷，烧结过程中，硫氧化钆原料饼料同时受到正压和高温的作用，其中的压力来源于混合气体，可以从各个方向对硫氧化钆进行施压，同时粉料处于热塑性状态，有助于颗粒的接触扩散、流动传质过程的进行和气体排出。因此能够降低烧结温度并缩短烧结时间，从而有助于抑制晶粒长大以及晶粒或颗粒之间气体的排出，进而有利于得到晶粒细小、致密度高的陶瓷产品，同时使得陶瓷材料的力学性能得到提高。
