SYNTHESIS AND TRANSFORMATIONS OF HYDRIDES UNDER HIGH QUASI-HYDROSTATIC PRESSURES

A method of synthesis and investigation of phase transitions of hydrid es under high quasihydrostatic pressures (up to 60 kbar in temperature range from ambient to 1400 K) is described. The transformations of al loys with compositions RTn, R2T (R-Zr, Ca, Ce, Er, T-Ni, Co) into hydr ides have been studied. The formation of new hydrides in the CaH2-Ni(C o) systems has been found.
