Ceramics based on lanthanum-doped barium titanate, method of preparation and uses |
摘要 |
The present invention relates to a method of preparing ceramics based on lanthanum-doped barium titanate, which comprises the following steps: (a) flash sintering of lanthanum-doped barium titanate powders; and (b) heat treatment of the material thus obtained, in an air atmosphere or in an oxidising atmosphere. The invention also relates to ceramics based on lanthanum-doped barium titanate, possessing a very high real part of the relative dielectric permittivity, and to their use for obtaining capacitors of high capacitance and high capacitance per unit volume for high-voltage withstand capability.
