Identification of alfa- and beta-phases of Si3N4 single crystals grown from Si melt could be made with the help of Vickers microhardness measurements. The effect of chemical additives, e.g. metallic Fe and BaF2, on the microhardness of Si3N4 was also determined. Different constants involved in the empirical Meyer relationship between load and indentation diameters could be correlated with the porosity and microhardness of Si3N4 single crystals and polycrystalline, reaction sintered Si3N4. © 1980 Chapman and Hall Ltd.
