Ultramarine pigment, although it is a widely demanded scarce material, is not produced in Kazakhstan, and huge needs are met through imports from other countries. Meanwhile, inorganic mineral pigments are among the priority materials in the State programs of industrial and innovative development of the Republic of Kazakhstan. To ensure high environmental friendliness, reduce costs it is advisable to use affordable and widespread pure natural raw materials. Therefore, studying the possibility of synthesizing silicate pigments based on selected highly effective mineral raw materials types and identifying patterns of solid-phase reactions during synthesis is an actual. The basis of scientific research consisted of mineralogical, petrographic and chemical analyses, petrochemical calculation of charges and comprehensive studies of the obtained samples. Original kaolin and silica raw materials were selected. The proposed synthesis advantage is to improve the charge technological qualities due to the use of high– grade kaolin and marshallite, which has a natural fine dispersion, high reactivity and ensures of chemical and solid-phase reactions throughout the entire volume of the charge at lower temperatures. The use of these components in the charge made it possible to obtain a bright saturated blue pigment and reduce its cost. The obtaining blue ultramarine possibility from local natural mineral raw materials has been demonstrated for the first time. The introduction of the developed technology for the synthesis of ultramarine pigment will solve the import substitution problem.
