Preparation and characterization on strontium barium niobate/barium strontium titanate composite ceramics by powder-sol method
0.3SrO·0.7BaO·yNb2O5·(1-y)TiO2 composite ceramics with different Nb/Ti ratios were,for the first time,fabricated using a Powder-Sol (P-S) method with Nb2O5 fine powders suspended in the barium strontium titanate (BST in short) sol solution.XRD results revealed that the tetragonal tungsten bronze (TTB) phase and perovskite phase were co-present in compositions.Scan electron microscope (SEM) results showed that composite ceramics are homogeneous and fine-grained.The chemical composition of 0.7BaO·0.3SrO·(1-y)TiO2.yNb2O5 composite ceramics were studied by X-ray photoelectron spectroscopy (XPS).
