Modification of basic refractory structure by zirconium dioxide nanopatricles

Abstract

The paper presents data on the influence of zirconium dioxide micropowder addition, partially stabilized by yttrium, on high-temperature resistance performance of fired periclase products, as well as on some physical and physical –mechanical properties. Microscopic examination of the structure of highpurity synthetic periclase and zirconium dioxide micropowder was carried out. The possible mechanism of interaction of the introduced additive with impurities contained in periclase was determined. Substantial influence of zirconium dioxide micropowder on high-temperature properties of refractory was established.
