ABSTRACT:
Titanates of zinc and/or alkaline earth metals are produced by simultaneously adding to a suspension of finely divided TiO.sub.2, maintained at a substantially constant pH above about 8, a solution of a salt of zinc and/or alkaline earth metal and alkali to form a hydroxide precipitate. Filtration produces a filter cake mixture of TiO.sub.2 and hydroxide and calcination at above 500.degree. C. produces the desired titanate of narrow particle size distribution and desirable optical properties. Non-simultaneous addition results in a non-filterable material. Zinc, magnesium and/or calcium are preferred and doping elements such as aluminum, phosphorus, boron and/or silicon may also be present.
