<title>Concentrated solid solutions and dissolution of diamond and cubic boron nitride</title>
Annotatsiya
The solubility in the multicomponent system is discussed. Considering the molecular elements and some combinations of elements not shown on the traditional phase diagrams as the new chemical compounds the conditions of the formation of their continuous solid solutions (CSS) with the single covalent bond are suggested. Using the valences and covalent radii of B, C, N, Be, O, Al, and P and possibility of the formation of CS, based on diamond and cubic boron nitride is substantiated. To back up such a possibility the brief review of the experimental data on the (IV<SUB>2</SUB>)<SUB>x</SUB>(III- V)<SUB>1-x</SUB> and (IV<SUB>2</SUB>)<SUB>x</SUB>(II-VI)<SUB>1-x</SUB> CSS are presented. Taking into account the advantages of thinning of chemical vapor deposited (CVD) diamond plates with a molten alloys and the idea on substitutional and interstitial liquid solutions for the processing of the polycrystalline CVD diamond plates by the effective dissolution a number of molten alloys are predicted.
