Abstract


The results of research of static characteristics of physical and mechanical properties obtained from the diagrams s = f(e) during tests of the crystallized in rolls-crystallizers plates of white (» 98  wt.% a-Al203) and zirconium (75 wt.% Al2O3 - 25 wt.% ZrO2) electrocorundum. A discussion on the influence of porosity, chemical and phase composition of ZrO2 on physical and mechanical properties of the plates and grinding of grain received during their shattering.
