Pigments based on pink corundum have been obtained by self-propagating high temperature synthesis in Cr2O3-Al2O3-Al system using a small amount of chromium oxide (up to 0.5 wt %) in the composition of the green mixture. Absorption bands of pink corundum in visible reflectance spectrum at λ=560 nm (17850 cm−1) and 400 nm (25000 cm−1) correspond to electron transitions 4А2g→4T2g(4F) and 4А2g→4T1g(4F). Increasing chrome oxide content to 5 wt.% in initial charge mixture leads to pigment darkening due to inclusions of Cr2O3. Synthesized pigments can be used as a component of glaze ceramic colors for porcelain
