Process for preparing titanates and zirconates

摘要

The invention concerns a process for preparing titanates and zirconates respectively of formulas MTiO3 and MZrO3 where M is Ba2+, Sr2+, Ca2+, Pb2+ and Mg2+ to the exclusion of MgZro3, consisting of reacting an ester of formula M[H-(CH2)nCO2]2 where n=1-4 with the formula M'[O(CH2)nCH2)nCH3]4 where M' is Ti or Zr bringing the reaction mixture to boil until the solvent is removed to yield a viscous translucent resin. The resin is cooled and further treated to obtain the desired product.
