Effect of impurities and sintering temperature on properties of MgO-CaZrO3 ceramic

Document type: Articulo

Abstract

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 3 agglomerates of variable size (~100µm) and MgO grains (size <50µm) containing some unreacted m-ZrO2 grains. The elastic modulus and flexural strength were correlated with the presence of impurities of the dolomite, porosity and microstructure of the ceramic.
