Investigation of the interaction of high-temperature metal melts with refractory concretes

The results of investigation of the interaction of high-temperature metal melts with alumina dioxide and zirconium dioxide concretes are presented. It was found that the erosion rate of the zirconium dioxide concrete is about a hundred times smaller than that of structural concretes at similar melt temperatures. The zirconium dioxide concrete is a candidate material for the core-melt catcher for a nuclear reactor.
