Abstract
Crystal structure and the phase transformation behavior of perovskite- type BaTiO3 and BaTiO3 ceramics with nanosized particulate SiC were in vestigated by simultaneous measurements of internal friction and shear modulus. The Curie temperature (T(c)) gradually decreased with increa sing particulate SiC content. In addition, the low-temperature transfo rmation disappeared at SiC content over 1 vol%. Diffused phase transfo rmation (DPT) was observed as the SiC content increased up to 3 vol%.
