摘要：
In this work, alpha-Al2O3 (1-40 vol%) particles (350 nm) were added to a 19.58Li(2)O.11.10ZrO(2).69.32SiO(2) (5 mu m) glass-ceramic matrix to prepare composites with the purpose of studying the influence of alpha-Al2O3 on their mechanical, thermal and electrical properties in order to obtain materials for LTCCs applications. The composites, sintered between 800 and 950 degrees C for 30 min, with relative densities between 85% and 93%, showed zircon and beta-spodumene as main crystalline phases. The maximum bending strength (290 MPa) was achieved for composites with 1% alpha-Al2O3. For composites containing between 1% and 10% alpha-Al2O3, sintered at 900 degrees C/30 min, the electrical and thermal conductivities and CTE varied between 3.35 and 1.21 x 10(-10) S/cm, 4.65 and 2.98 W/m K, 9.54 and 3.36 x 10(-6)degrees C-1, respectively.
