摘要
通过改变氧化铝粉浆的粉液比、预烧温度以及成型工艺等参数,研究了以上因素对用于制作全瓷冠桥的In-Ceram玻璃渗透氧化铝陶瓷复合体性能的影响。研究发现,在粉液比为7:1的复合体中,颗粒分布均匀,性能较好;2次渗透组比1次渗透组性能要更好;对于不同预烧温度煅烧的样条,1150℃的强度最好;采用注浆成型的毛坯比干压成型的强度要高。结果表明粉液比7:1、注浆成型2次渗透组强度较高,达到529.8MPa。
The fabrication process of glass infiltrated alumina ceramics （in-ceram alumina） was investigated, such as changing powder/liquid ratio, pre-sintered temperature and forming method. The result indicates that the powder-liquid ratio of 7：1 sample has better bending strength, two-time infiltrated sample also has better bending strength than one time sample, and comparing with 1450 ℃, the 1150 ℃ pre-sintered sample has better bending strength. Two-time infiltrated slip-casting sample with 7：1 powder/liquid ratio has a bending strength as high as 529.8 MPa.
