Originální abstrakt

The mechanism and the course of high temperature corrosion of refractory castable based on alumina cement and mullite aggregate was investigated by scanning electron microscopy (SEM) and high temperature X-ray diffraction (HT-XRD). The low carbon monoxide resistance leads to the material failure at temperatures significantly lower than it can be supposed from the used raw materials. The carbon stored in the refractory material as the consequence of equilibrium Boudouard - Bell reaction is concentrated in the matrix – the opening material interface where the low temperature eutectic melts under reduction condition were formed. In paradox the grain of opening material considered as the temperature more resistant phase is dissolved at first and it forms the melts penetrating the matrix, hence the opening materials grain is replaced by cavity.
