Аннотация: The subject of this research is phasic transformations of quartzites that are under temperature treatment to remove moisture. This technology is used in enterprises operating melting furnaces. The studies have shown that using a temperature regime consisting in heating to 800°C and holding for 2 hours, after cooling, quartzite chanПоказать полностьюges its color and appears a shift in the angle of the interplanar distances of the crystal lattice by 6.6% in it. The use of a temperature treatment regime consisting in heating to 200°C and holding for 4 hours does not reveal such changes. With subsequent exposure to these samples of the temperature regime corresponding to the sintering process of the liner, the following is established. In a sample pretreated with a temperature of 800°C, at a temperature of 1550°C, a tridymite phase appears. In the sample of a 200°C pretreated with temperature, a phase of cristobalite appears without tridymite. © Published under licence by IOP Publishing Ltd.
