The new boride ErNi7.9B2 is synthesized, and its crystal structure is determined by single-crystal x-ray diffraction: sp. gr. C2/c, new structure type, a= 1.6626(2) nm,b = 0.9525(1) nm,c = 1.0686(1) nm, β = 117.76(1)°, RF = 0.0399. The crystal-chem

The phase diagram of the ternary Yb–Ni–B system at 1070 K has been built using the results of X-ray diffraction. As a result of our research the existence of six ternary borides has been confirmed, the composition of the borides YbNi7B3 (space gr

Isothermal sections at 1070 K have been constructed by x-ray diffraction applied to the phase diagrams in the Tm - W - B and Lu - W - B systems. The solubility of “WB2” in TmB2 is low, while that in LuB2 attains 0.15 molar fraction (lattice param

X-ray structure analysis has been used to construct isothermal sections at 1270 K for the phase diagrams for the Y - Mo - B and Tm - Mo - B systems. The solubility of MoB2 in YB2 is low, while that in TmB2 is not more than 0.05 molar fraction (lattic

X-ray diffraction data have been used in compiling equilibrium phase diagrams for the Lu−Cr−B and Lu−Mo−B systems at 1270 K. The boride LuB2 dissolves not more than 0.03 molar part of CrB2 and 0.30 molar part of MoB2. The existence of compoun

The results of experimental investigations of reactions of rare-earth (Ln) and transition (MeVI, VII) metals with boron were reviewed. An analysis of the phase equilibrium diagrams of 50 Ln−Me−B systems was carried out. The laws of formation of t

We have used x-ray phase analysis to establish the phase equilibria at 600°C for the systems Gd-Al-B, Tb-Al-B, and Ho-Al-B (the boron-rich sites have not yet been studied). We determined the crystalline structure of the new borides HoAlB4 and ErAlB4
