摘要: Abstract Barium strontium titanate (Ba 1- x Sr TiO 3 , BST) and barium niobate (Sr Ba Nb 2 O 6 SBN) are important ferroelectric materials with excellent pyroelectric, dielectric properties faster response time of infrared radiation. SBN/BST composite ceramics different mole ratios Ti were fabricated using a powder-sol (P-S) method 5 fine powders suspended in the (BST short) sol solution. The X-ray diffraction results indicate that three intermediate phases, i.e. BaNb SrNb developed during formation SBN-BST. Powders obtained from dried gels calcined at 800 ? for h. 2p spectra only one spin-orbit doublet observed, which indicates 4+ chemical state ceramics. binding energies element depend strongly on composition.
