The purpose of the present work was to prepare a series of pigments SrVxSn1-xO3 (x = 0; 0.025; 0.05; 0.1; 0.2 and 0.3) by classical ceramic method and by simulation of 'mixer dryer reactor' in the temperature range 1,300-1,500 A degrees C. These compounds belong to group of high-temperature pigments. The principal of these pigments makes the host lattice of the SrSnO3, which is doped by vanadium ions. This incorporation of the doped ions leads to obtaining of the interesting yellow colour after application into the organic matrix. The fired pigments were characterised by TG-DTA analysis, scanning electron microscopy and colour measurements. The particle size was measured and X-ray diffraction analysis was also performed to define character of the new compounds. Pigments of brighter yellow colour were obtained for the V concentration 0.025 at calcination temperature 1,475 A degrees C. Most pigments meet given range of the mean particle size distribution d (50), which is a necessary condition for the pigments to be applicable in a binder.
