Lanthanum germanides

  • Published:
Soviet Powder Metallurgy and Metal Ceramics Aims and scope

Summary

The authors have investigated the conditions of preparation of the lanthanum germanides LaGe2, LaGe, and La5Ge3 by synthesis from the elements in an arc furnace, and of lanthanum digermanide by the germanium-thermic method. Some chemical properties of lanthanum germanides-stability of germanide powders in water and thermal stability in air and in an ammonia atmosphere-were studied. It is shown that the oxidation of the germanides passes through the stage of formation of lanthanum oxygermanides. During the reaction of lanthanum monogermanide with ammonia, LaGeN is formed as a product.
