The effect of strong deviations from stoichiometry in the structural type of fluorite (CaF2) on the microhardness of Ba0.9R0.1F2.1 crystals (R is the rare earth elements La-Lu) has been studied. Mechanical hardening of heterovalent Ba0.9R0.1F2.1 solid solutions in comparison with the BaF2 matrix is due to the formation of nanosized clusters of point defects [Ba8R6F69], replacing structural fragments [Ba14F64] (block type of isomorphism). It was found that, with a decrease in the cluster size from [Ba8La6F69] to [Ba8Lu6F69], the microhardness of nanostructured Ba0.9R0.1F2.1 crystals increases by 73%.
