The microstructure and microwave dielectric properties of dolomite type borates, CaZr(BO3)2 ceramics prepared by conventional mixed oxide method were explored. The sintering temperature of CaZr(BO 3)2 ceramics could be reduced from 1150°C to 925°C with little amount of sintering additives. Microwave dielectric properties of 3 wt% Bi2O3-CuO added CaZr(BO3)2 ceramics sintered at 925°C were K ≈10.4, Q × f ≈80,000 GHz and TCF≈+2 ppm/°C Thus obtained LTCC tape was co-fired with Ag paste for compatibility test and revealed no sign of Ag reaction with the ceramics. Therefore, CaZr(BO3)2 ceramics is considered as a possible candidate material for low temperature co-fired multilayer devices.
