Abstract MnO addition had a remarkable effect on the microstructure, mechanical and electrical properties of BaO-Al2O3-B2O3-SiO2 glass-ceramics. The crystallizing behavior was investigated by the whole pattern fitting method. The sintering kinetics was also studied based on the shrinkage rate curves. The result showed that 1 wt% MnO addition effectively promoted crystallization and densification. It was found that the high crystallinity as well as the large grain size contributed to the strong bending strength and Young’s modulus. For the sample doped with 1 wt% MnO, bending strength and Young’s modulus increased significantly from 136.3 MPa to 201.2 MPa and 59.7 GPa to 79.7 GPa, respectively.

添加MnO对LTCC应用BaO-Al2O3-B2O3-SiO2微晶玻璃微观结构和性能的影响

摘要 添加MnO对BaO-Al2O3-B2O3-SiO2微晶玻璃的微观结构、力学和电学性能有显着影响。通过整体图案拟合方法研究结晶行为。还基于收缩率曲线研究了烧结动力学。结果表明，1 wt% MnO 添加有效地促进了结晶和致密化。发现高结晶度以及大晶粒尺寸有助于强弯曲强度和杨氏模量。对于掺杂 1 wt% MnO 的样品，弯曲强度和杨氏模量分别从 136.3 MPa 显着增加到 201.2 MPa 和 59.7 GPa 到 79.7 GPa。
