High Pressure Synthesis and Crystal Chemistry of Metalloid-Rich Intermetallic Compounds

Abstract

High pressure technique still appears to be an important tool for the synthesis of advanced new materials. The current topics of high pressure synthesis of intermetallic phases, achieved in our laboratory, are presented and discussed in terms of crystal chemical aspect. The phase transition sequences in transition metal dipnictides and dichalcogenides are schematically summarized. The other topics include the synthesis of novel macro-tetrahedral compounds in boro-sulfide system and the atom insertion into the cage of the skutterudite host lattice.
