Abstract

The effect of grinding MgTiO3 on the particle size and electrical properties was studied. Initially, good dispersion conditions were optimized via rheological characterizations of the aqueous slurry in variant dispersant amounts. Then, 50% MgTiO3 slurry was grinded using balls of different diameter sizes (0.8 and 0.4 mm) for two consecutive cycles. The milled powder was characterized using laser granulometry, BET method, X-ray diffraction and scanning electron microscopy techniques. The crystallite size was calculated using Halder-Wagner methods. The electrical and dielectrical properties were also monitored for different particle size. These results revealed impurities from the zirconium balls, however, without affecting the particle size even if prepared with different grinding operations.
