Abstract

Plated-like Bi₄Ti₃O₁₂ powder with anisotropy was prepared by NaCl-KCl molten salt method. Effects of calcination temperature and salt quantities on anisotropic microstructure of Bi₄Ti₃O₁₂ powder were investigated. The rate of radial size to thickness size of plated-like Bi₄Ti₃O₁₂ powder was calculated to express the degree for anisotropy. The results show that the Bi₄Ti₃O₁₂ particle size and the degree of anisotropy increase with the increasing calcination temperature and molten salt quantities. The best calcination temperature is 950°C. The textured Bi₄Ti₃O₁₂ ceramics with plated-like grain can be obtained by sintering Bi₄Ti₃O₁₂ powder with large anisotropy at 1100°C.
