| Abstract: | BaTi4O9-doped Ba0.6Sr0.4TiO3(BST) composite ceramics were prepared by the conventional solid-state reaction and their structure,dielectric nonlinear characteristics and microwave dielectric properties were investigated.The secondary phase of the orthorhombic structure Ba4Ti13O30 is formed among BST composite ceramics with the increase of BaTi4O9.At the same time,a duplex or bimodal grains size distribution shows fine grains in a coarse grain matrix.The degree of frequency dispersion of dielectric permittivi... |
