Description
| - The metal-rich portion of the Co-Ni-P system was studied experimentally at 800 oC by means of evacuated silica glass tube technique. Five binary phases: Co2P, Ni2P, Ni12P5, Ni5P2, Ni3P and five ternary phosphides solid solutions: (Co1-x, Nix)3P, ?1-(Ni1-xCox)2P (hexagonal), ?2-Co1-xNix)2P (orthorhombic),(Co1-x,Nix)12P5 and (Co1-x,Nix)5P2 were found to be stable in the system. Cobalt has a significant influence on the structure of (Ni,Co)2P solid solutions and, therefore, cobalt contents might change the crystal structure of naturally occurring phosphides with the Ni/P = 2:1 ratio. Ni-rich, cobalt-containing phosphides with the Ni/P ratio = 3:1 and 2:1, isotypic with minerals schreibersite and barringerite, could possibly be found in meteorites. Likewise, phosphides with Ni/P ratio = 12:5 and 5:2 may possibly be found, but in close association with natural Ni-rich phosphides.

- Fázové vztahy v kovy bohaté části soustavy Co-Ni-P byly studovány v zatavených, evakuovaných kamenných trubicích. V soustavě bylo identifikováno pět binárních fází: Co2P, Ni2P, Ni12P5, Ni5P2, Ni3P a pět ternárních pevných roztoku: (Co1-x, Nix)3P, ë1-(Ni1?xCox)2P (hexagonální), ë2-Co1?xNix)2P (ortorombický),(Co1-x,Nix)12P5 a (Co1-x,Nix)5P2. Kobalt má významný vliv na strukturu Ni-Co fosfidu. (cs)
