[en] Investigation results of lithium, sodium and potassium interaction with tellurium dioxide at 1073-1223 K are presented. Decrease of the value of polyphosphate average molecular mass and melt viscosity by the growth of tellurium dioxide content in initial impurities, temperature and interaction time is stated. Polyanion destruction is confirmed by tetra-, piro-, orthophosphate availability in hardened interaction products. Tellurium dioxide interaction with polyphosphate was followed by formation of tellurium (6) compounds

[en] Mixed monocrystal uranium and rare earth selenides of the composition Ln2U2Se7 (Ln = Tb, Dy, Ho, Er, Tm, Yb, and Y) are prepared. X-ray study is conducted. Compounds Ln2U2Se7 are crystallized in monoclinic crystal system. Spatial group is C2, Cm or C2/m. Parameters of crystal lattices are measured. A compound similar in composition to Yb2U2Se7 is crystallized in rhombic crystal system

[en] By the method of DTA in soldered platinum ampoule the melting temperature of InF3, being 1320±10 deg C, was determined. It is detected that when kept in the air InF3 reacts with atmosphere. Using the methods of DTA and X-ray phase analysis, phase equilibria in systems LiF-InF3 and YbF3-InF3 are studied. In the first system compounds Li3InF6(two modifications) and LiInF4 are found, in the second one-solid solutions on the basis of the components
