Method for preparing flaky monocrystal lanthanum bismuth titanate powder by molten salt method

The preparation method for platy-monocrystal LBT as ferroelectric material comprises: weighing analytical-pure Bi2O3, La2O3, and TiO2 according to the Bi4-xLaxTi3O12 with mass ratio to molten NaCl as 1-30; grinding the mixture in ethanol solution evenly; finally, drying, calcining at 820Deg. This in...

More Information
Summary:The preparation method for platy-monocrystal LBT as ferroelectric material comprises: weighing analytical-pure Bi2O3, La2O3, and TiO2 according to the Bi4-xLaxTi3O12 with mass ratio to molten NaCl as 1-30; grinding the mixture in ethanol solution evenly; finally, drying, calcining at 820Deg. This invention can select different temperature and time to control product shape and size with low cost and short period, and promotes Bi4-xLaxTi3O12 application.
