Physical and mechanical properties of electrocorundum plates, crystallized in roll-crystallizers

The results of research of static characteristics of physical and mechanical properties obtained from the diagrams σ= ϕ(ε) during tests of the crystallized in rolls-crystallizers plates of white (≈ 98 wt.% a-A1 20 3) and zirconium (75 wt.% Al 2O3 - 25 wt.% ZrO 2) electrocorundum. A discussion on the influence of porosity, chemical and phase composition of ZrO 2 on physical and mechanical properties of the plates and grinding of grain received during their shattering.
