Barium Magnesium TantalateLorad scientists have developed a procedure for the manufacture of a stoichiometric Barium Magnesium Tantalate product. A typical x-ray diffraction pattern is shown in Fig1. It turns out that the precise control of the Ba:Mg ratio is easily verified by XRD whereby quite small deviations in stoichiometry produce additional maxima designated to established ordering and lattice occupancy in perovskite structures.
By careful control of raw materials and processing conditions, a phase pure material is obtained having a laser diffraction measured D50 < 10 microns, and typically near to 6 microns. This yields a material with acceptable industrial sintering characteristics.
