Abstract
Submicron grinding of BaTiO3 powder was studied with a vibration ball mill using alumina balls from 30mm to 1mm in diameter. BaTiO3 clinker obtained by calcining of an equimolar mixture of BaCO3 and TiO2 was preground to 1.95μm. The average particle size was calculated from specific surface area measured by BET method. The results obtained are summarized as follows;<br>(1) Submicron grinding of BaTiO3 powder was possible with small balls in short time on the factory base.<br>(2) With balls of 1mm in diameter, the minimum specific surface area diameter (Ds) was 0.026μm in one milling operation.<br>(3) The following empirical relation was obtained, log(SS)=-0.588logr+1/2logt+0.701 where SS is, specific surface area, r is ball radius and t is time.
