Japanese Patent JP2000513700
Kind Code:
A
Abstract:
The present invention is concerned with a titanium-, -and alkaline- or alkaline-earth-based compound, processes for the preparation thereof, and use thereof as a coloring pigment. The product of the invention is characterized in that it corresponds to formula (1) MxCeyTizOt wherein M represents an alkaline or an alkaline-earth, and x, y and z satisfy the following equations: 0.1<=y/z<=1.5, 1<=(x+z)/y<=15, x+y+z=1, (x+3y=4z)/2<=t<=(x+4y+4z)/2. The product can be prepared by forming a mixture which comprises a titanium salt, sol or suspension, a compound of element M, and a cerium compound and then by drying and calcining the mixture, thus formed, according to a second variant, the compound is prepared by bringing together a cerium compound and a titanium compound in a liquid medium; by adding a base to the mixture thus obtained, whereby a precipitate is obtained; by bringing together a compound of element M and the precipitate thus obtained; by drying and then calcining the mixture obtained.
