Study on preparation and performance of LTCC with lower sintered temperature

Based on the Bi-B-Si fusible glass,we prepared the low-temperature co-fired ceramic(LTCC) powders by the way of the fusible glass + ceramic with the direct calcination method,whose sintering temperature was below 700℃.A type of LTCC powders with dielectric constant about 9.0,low dielectric loss about 0.003 @ 500MHz was prepared by controlling the ratio of glass phase and ceramics,which can be sintered at 630℃.
