Abstract
A titanium acylate solution is produced by adding glacial acetic acid to tetra-isopropyl titanate. Distilled water is then added until the solution clears, and a high grade alkaline-earth metal carbonate, such as BaCO.sub.3, SrCO.sub.3 or CaCO.sub.3, or a combination thereof, is added and agitated until the earth-metal dissolves and the solution again becomes clear. An alkaline hydroxide, such as NaOH, is added until the pH of the solution reaches 13 or 10 above, and causes crystals of an earth-metal titanate to form in the solution. The solution is thereafter filtered to produce an alkaline-earth metal titanate filter cake which is then dried and washed to produce the desired powder. At no time during the process is it necessary to apply any external heat to the solution. The heat of reaction is sufficient.
