Abstract
Ultrasonic agitation is a very efficient method for deagglomeration and dispersion of ceramic slurries (alumina and barium titanate). The influence of parameters such as acoustic power, temperature, and treatment duration on the dispersion efficiency has been studied. For optimum conditions, very short times (2-3 min) of ultrasonic agitation are enough to obtain well dispersed, stable slurries. The role of aging of slurries has also been examined
