| 摘 要： | 以CaO-MgO-SiO2玻璃为烧结助剂,对液相烧结Al2O3/3Y-TZP(30%体积分数)复相陶瓷的致密化机理进行了研究.结果表明,适量的烧结助剂可以显著促进材料的致密化,液相烧结激活能为169 kJ/mol,表明扩散控制为其致密化机理.

| Abstract: | Al_2O_3/3Y-TZP composite was sintered isothermally in air with the addition of CaO-MgO-SiO_2 glass.The densification mechanism of the composites was investigated.It was found that appropriate amount of CaO-MgO-SiO_2 glass could greatly improve the densification of the composite.The measured activation energy is 169 ?kJ/mol,which suggest that diffusion is the controlling mechanism for the Al_2O_3/3Y-TZP composite by liquid phase sintering. |
