Abstract
A crystalline metal oxide in the form of a solid solution comprising an oxide of a metal of Group II of the periodic table, titanium oxide and silicon dioxide as main components and having main peaks at about 26.7.degree. and about 20.9.degree. in its Cu-K.alpha. X-ray diffraction pattern (2.theta.) and a specific refractive index. The crystalline metal oxide is produced, for example, by dissolving a compound of a metal of Group II of the periodic table, a hydrolyzable organic silicon compound and a hydrolyzable titanium compound in an organic solvent, hydrolyzing said starting compounds in said solution or after said solution is added to a separately prepared solvent incapable of dissolving the reaction product, thereby to form a sol- or gel-like product, and thereafter calcining the sol- or gel-like product at a temperature and for a period of time sufficient to crystallize said product.
