摘要
Fibrous Batium Titanate particles, 30 50 μm long, prepared by a hydrothermal reaction, and the monoclinic phase and nanometer Zirconia, 11.6 nm long were prepared by citric acid reaction respectively. Then, the two were composite sintered to produce a new functional material by making full use of crystal axis orientation of fibers and the activity of nanometer powder. The analydid of composition and microstructure of the new material in terms of XRD and SEM. shows that the solid solution was formed between fibers and nanometer powder, and the distance between lattice (d value) of Barium Titanate changed. But the crystal axis orientations of fibers remain unchanged.
