本文将α-Al2O3（1-40 vol%）颗粒（350 nm）添加到19.58Li2O·11.10ZrO2·69.32SiO2（5µm）玻璃陶瓷基体中，制备复合材料，研究α-Al2O3对复合材料力学、热学和电学性能的影响，以获得ltcc应用材料。复合材料在800 ~ 950℃下烧结30 min，相对密度在85% ~ 93%之间，主要晶相为锆石和β-锂辉石。当α-Al2O3含量为1%时，复合材料的最大抗弯强度为290 MPa。在900℃/30 min烧结时，α-Al2O3含量在1% ~ 10%之间的复合材料的导热系数和CTE分别在3.35 ~ 1.21×10−10S/cm、4.65 ~ 2.98 W/m K、9.54 ~ 3.36×10−6℃−1之间变化。
In this work, α-Al2O3(1–40 vol%) particles (350 nm) were added to a 19.58Li2O·11.10ZrO2·69.32SiO2(5 µm) glass-ceramic matrix to prepare composites with the purpose of studying the influence of α-Al2O3on their mechanical, thermal and electrical properties in order to obtain materials for LTCCs applications. The composites, sintered between 800 and 950 °C for 30 min, with relative densities between 85% and 93%, showed zircon and β-spodumene as main crystalline phases. The maximum bending strength (290 MPa) was achieved for composites with 1% α-Al2O3. For composites containing between 1% and 10% α-Al2O3, sintered at 900 °C/30 min, the electrical and thermal conductivities and CTE varied between 3.35 and 1.21×10−10S/cm, 4.65 and 2.98 W/m K, 9.54 and 3.36×10−6°C−1, respectively.
