摘要: This paper is concerned with intermetallic compounds between the A elements thorium, uranium, and plutonium X from chromium group through Si group. Thorium, U, Pu differ transition in crystal structure of their com pounds, that Th, form definite stoichiometric ratios never sigma phases or other which are characterized by variable composition. Furthermore, thoride tend to an average atomic volume greater than predicted volumes elements, while generally show a contraction volume.
