Abstract : A series of semiconductor heterovalent compounds (divalent and trivalent) forming five developed iso-electronic series were prepared. The members of these series have the diamond, zinc blends, and chalcopyrite structures or ones close to them. The general tendence of change in microhardness in these series is a lowering with a gain in ionic quality. Measurements on monocrystalline objects apparently will provide the possibility of refining this conformity to law. The qualitative consideration of the dependence of the microhardness on the composition in the isovalent solid solutions of diamond-like substances enables one to draw the following conclusion: this dependence is reflected by a smooth curve (in accordance with Kurnakov's law.) As is shown by observation in the majority of the systems this maximum will shift in the direction of the harder component.
