Abstract
Theoretical prerequisites are given for the formation of boride phases in castings. Lithium borides LiB2 and LiB10 are synthesized and identified by x-ray photoelectron spectroscopy and x-ray phase and chemical analyses. Lithium diboride is a rather unstable compound which easily decomposes in weak mineral acid solutions. In contrast the decaboride is highly resistant to corrosive media. It decomposes completely in HNO3-H2O2 and H2SO4-HNO3 mixtures. A small amount of boron hydride is released as a result of lithium decaboride reaction with acids. Some physical properties (magnetic susceptibility, resistivity) are studied. The physicochemical properties of the Li-B system resemble those of the Be-B system. The highest lithium boride LiB10 pertains to covalent crystals and like boron it possesses semiconducting properties.
