Abstract
PURPOSE: To obtain an ultramarine pigment having a clear blue color and finely divided uniform particle diameters, by heating a blend of zeolite and an alkali metallic sulfide or a blend of zeolite, sulfur, a source of an alkali metal, and a reducing material.
CONSTITUTION: A blend of one or more kinds of zeolite having particle diameters of 1W5μ slelected from the group consisting of A-type, X-type, and Y-type zeolite and an alkali metallic sulfide shown by the formula A2Sx (A is an alkali metal element; x is 1W5) or a blend of the above-mentioned zeolite, sulfur, a source of an alkali metal, e.g., Na2CO3 or NaOH, and a reducing substance, e.g., carbon black is heated in a non-oxidizing atmosphere at 600W900°C for about four hours to give an ultramarine green pigment. The ultramarine green pigment is then heated in an oxidizing atmosphere at 300W600°C for about four hours to give an ultramarine blue pigment.
