摘要
利用氧化锆的相变能够提高材料韧性的作用,在MgO-Al2O3-SiO2微晶玻璃中添加部分稳定超细氧化锆,用烧结法制得微晶玻璃基板。使用AKASHI压痕法测试材料增韧前后的韧性,利用FESEM观察微晶玻璃断口形貌,用XRD测试样品中的晶体组成,并在多芯片基板上初步得到满意的使用效果。实验证明,添加一定量的超细氧化锆后微晶玻璃的韧性有很大的提高,基板的破损率有较大的降低。
The phase transition of zirconia can improve the toughness of material. Superfine partially stabilized zirconia was added into MgO -Al2O3 -SiO2 glass -ceramics and the glass -ceramic substrate was prepared by sintering method. The toughness of glass - ceramics before and after toughening was examined by AKASHI indentation, the fracture morphology of glass - ceramics was observed by FESEM, and the crystalline composition was measured by XRD. This material was also used in multichip substrate successfully. The research results show that the toughness of the glass - ceramics can be improved significantly by adding a certain amount of superfine partially stabilized zirconia powder and thus the defective rate of substrate can be decreased sharply.
