In this study, the effect of specific rates of breakage of nefelinli siyenit, which is a magmatic, feldspathic rock, on technologicalproperties of ceramic bodies is examined. The ceramic material properties considered in this study derived from theapplication of non-destructive and destructive tests and include firing shrinkage, water absorption, mercury porosimeter andfiring strength, while the specific rate of breakage (Si) determined from batch grinding tests. In order to Si values, in the rangeof -63+53 μm mono-size fraction was prepared. The nepheline syenite prepared in these interval were ground with 1/4, 5/16,3/8, 1/2 and 3/4 inches alloy steel balls for different durations. The results indicate that the technological properties of ceramicmaterials examined show very good correlation and can be used to predict Si. Overall, it is deduced that multiple regressionanalysis involving two independent variables is a reliable approach and can be used to identify correlations betweentechnological properties of ceramic materials and specific rate of breakage values for nepheline syenite.
