摘要：

Barium titanate and alumina mixed (from 0.5 to 5vol.%) barium titanate composite ceramics incorporating nano-sized powders were prepared by the conventional electroceramic process. With the increase of alumina addition content, the densities of the ceramics gradually decreased from 5.67g/cm(3) to 5.3g/cm(3), the hardness was enhanced, and the phase transition from tetragonal to cubic became disperse. Comparable dielectric and piezoelectric properties of barium titanate ceramics could be obtained when the alumina addition content was no more than 1vol.%.
