蔡老师来帮你了,英语专业的,但是我觉得你中文表达有的地方挺别扭的。你看看吧,有何问题再说。 !蔡氏招牌,成就未来!γ-Al2O3 preparation and manufacture of crystalline ceramicsSun Wenzhou; Ma Jianjun; Qin Yingjie; Qi Xiuyuan; He Deng; Ma Deliang ;Xu Ke(Yinchuan 750021 Material Science and Engineering institute,The northern nationalities university )Abstract: According to different proportion,this text taking nanoscale high-purity Y-A203,AIN and Al power for materials, uses Y203 and Mgo as sintering aids。Firstly, get the Preloading molding and cold isostatic pressing molding under 16。7 and 250 MPa respectively。Secondly use Solid phase sintering process under 1800℃ for 6 hours in nitrogen to gain Aluminum Oxynitride (AlON) with mechanical and optical characters to some extend。 It turns out that, the end product will possess the best light transmittance when Y-A203 comparing to AIN was used at the proportion of 3 to 7 mol%。 X-Ray Diffraction(XRD) phase test showed that,the resultant mainly containes AION, little solid solution of Al203 and MgO。Key words: crystalline ceramics,Aluminum Oxynitride ,solid phase sintering,and cold isostatic pressing molding
