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 $\sigma=\phi(\varepsilon)$ during tests of the crystallized in rolls-crystallizers plates of white ($\approx98$ мас.% $\alpha$-$\mathrm{Al_2O_3}$) and zirconium ($75$ мас.% $\mathrm{Al_2O_3}$ — $25$ мас.% $\mathrm{ZrO_2}$) electrocorundum. A discussion on the influence of porosity, chemical and phase composition of $\mathrm{ZrO_2}$ on physical and mechanical properties of the plates and grinding of grain received during their shattering.
