我们成功地在CaO-Al_2O_3-SiO_2相图中识别和制备了玻璃成分，并对熔剂进行了明智的选择，以满足低温共烧陶瓷(LTCC)的所有介电、电和热性能要求。在900℃下烧结的玻璃组分具有良好的密度(2.45g/cc)，不会析出任何晶相。然而，当该玻璃粉末在相同温度下烧结时，在30体积%的堇青石存在下，观察到钙长石相的析晶，这改善了复合材料的性能，用于低温共烧陶瓷。
We report successful identification and preparation of a glass composition in the CaO-Al2O3-SiO2 phase diagram with a judicious choice of fluxes that met all dielectric, electrical, and thermal property requirements for low-temperature cofired ceramic (LTCC) applications. The glass composition sintered at 900 degrees C attains good density (2.45 g/cc) and does not precipitate any crystalline phase. However, when this glass powder is sintered at the same temperature in the presence of 30 vol% cordierite, crystallization of the anorthite phase is observed, which improves the properties of the composite for LTCC application.
