In the metal-rich portion of the system Co-Ni-P at 800 degrees C, five binary phases: Co (sub 2) P, Ni (sub 2) P, Ni (sub 12) P (sub 5) , Ni (sub 5) P (sub 2) , Ni (sub 3) P, and five ternary phosphide solid solutions (Co (sub 1-x) Ni (sub x) ) (sub 3) P, lambda (sub 1) -(Ni (sub 1-x) Co (sub x) ) (sub 2) P (hexagonal), lambda (sub 2) -(Co (sub 1-x) Ni (sub x) ) (sub 2) P (orthorhombic), (Co (sub 1-x) Ni (sub x) ) (sub 12) P (sub 5) and (Co (sub 1-x) Ni (sub x) ) (sub 5) P (sub 2) were found to be stable in the system. Cobalt has a significant influence on the structure of (Ni,Co) (sub 2) P solid solutions and Co contents might well change the crystal structure of naturally occurring phosphides with Ni/P = 2:1 ratio. Ni-rich, Co-bearing phosphides with Ni/P 3:1 and 2:1, isotypic with schreibersite and barringerite, could possibly be found in meteorites. Likewise, phosphides with a Ni/P ratio of 12:5 and 5:2 may possibly be found, but in close association with natural Ni-rich phosphides.
