Reducing the sintering temperature without affecting the properties is a challenging problem in LTCC material research. Low melting glass addition, chemical processing and small particle size of starting materials are three main methods normally used to reduce the sintering temperature of these dielectric ceramics. However, fine powders prepared by wet chemical processing such as the sol–gel process complicate the fabrication method and increase the cost. Addition of low melting glass either leads to poor microwave dielectric properties or significantly increases the possibility of chemical interaction with the metal electrode due to the presence of complicated phases in the LTCC system [1, 2]. So, a glass-free LTCC material with appropriate microwave dielectric properties is strongly desired for the multilayer structure applications. A number of glass-free LTCC materials have been reported [3, 4, 5, 6, 7, 8, 9, 10]. However, most of these materials have a high τf, which is a key...
