The gravitational sedimentation of particles in a dispersion are a major concern of many industries. The pharmaceutical industry requires uniformity and long-term stability so that dose rates can be accurately controlled. The ceramic and foodstuff industries require short-term stability for production processes. The paint and printing ink industries control stability in order to obtain desired gloss, durability and flow properties of both aqueous and non-aqueous dispersions. Since dispersions of barium titanate are a prime consideration in the field of electroceramics, and since there is a lack of information on this subject the author felt that a study of the sediment volumes and settling rates of barium titanate in water and methyl isobutylketone would be of value.
