Effect of impurities and sintering temperature on properties of MgO-CaZrO3 ceramic [PDF]
, 2013 CaZrO3 -MgO ceramics are useful as refractories in kilns for the cement production. One method of manufacture of such ceramics is by sintering from m-ZrO2 and dolomite MgCa(CO3 )2 mixtures. In this work electrofused m-ZrO2 grains (fraction
