Synthesis, structure and properties of BaZrxTi1-xO3 center dot yLa(2)O(3) solid solutions

A series of BaZrxTi1-xO3 . yLa(2)O(3)(0 less than or equal to x less than o r equal to 0.3, 0 less than or equal to y less than or equal to 0.04) solid solutions were synthesized by means of soft chemical method at 95 degrees C. XRD and d-spacing-component figures of the series of the solid solutions proved that the compounds are mutual miscible in the solid solutions, Furt her, through a TEM, the product is found to have a shape of uniform, substa ntially spherical particles with an average particle diameter of 60 nm. The result of preparing ceramics showed that adulterating with zirconium and l anthanum in pure BaTiO3 phase obviously improved the dielectric constant at normal temperature.
