The System Yb-Co-P

Budnyk S., Kuz'ma B.

Polish Journal of Chemistry

2002

Vol. 76 / nr 11

1553-1558

Phase equilibria in Yb-Co-P system have been investigated at 870 K by X-ray analysis. The existence of early known compounds Yb2Co12P7 (structure Zr2Fe12P7), YbCo5P3 (structure YCo5P3), YbCo3P2 (structure HoCo3P2), Yb6Co30P19 (own structure) and Yb5Co19P12 (structure Sc5Co19P12) has been confirmed. Atomic coordinates in structures Yb2Co12P7 (powder method RF = 0.049) and YbCo3P2 (single crystal method, RF = 0.0393) have been determined.

Phase Equilibria in Y--Ag--P and nd--Ag--P Systems

Phase equilibria were established in the Y-Ag-P and Nd-Ag-P ternary systems up to 80 at.% of P at 400°C. The isothermal sections have been built basing on X-ray phase analysis.
