The results of studies of the effects of high temperatures on high-refractory unshaped materials based on refractory oxides and silicides are given. The effect of mineral additives on their characteristics and physicomechanical characteristics is also shown. It has been established that unshaped aluminosilicate materials based on electrofusion or tabular material are able to work without loss of their properties at operating temperatures not lower than 1600 ºC. The introduction of carbon or basalt microfiber into the material makes it possible to reduce the volume and diameter of coronal refractories, but at the same time increases their linear average when exposed to high temperatures.
