Information is given on various types of fused-cast chrome-containing refractories ― chromalumozircon and chromium spinelids. It is shown that the chromium spinelids refractories HPL-85 and HMG are at the same level with the ceramic refractories made of chromium oxide in terms of corrosion resistance in melts of alkali- free borosilicate glass E, mineral wool, basalt fiber, etc. The problems of the presence and formation of hexavalent chromium in the production of chrome- containing materials are discussed. It is shown that the production of fused-cast chrome-containing refractories is possible under safe production conditions. The necessity of creating an industrial production of fused chromium-containing refractories based on domestic developments, taking into account the best foreign achievements, is noted.
