ABSTRACT:
A process for producing barium titanates which comprises admixing a titanium alkoxide with a barium salt of a lower carboxylic acid in the presence of an organic solvent containing at least ethylene glycol monomethyl ether to provide a uniform mixture, bringing the mixture in contact with water to form a gelated product and drying and calcining the gelated product.
