Abstract:

The intermetallic compound YCo5 promises to be an excellent material for high quality permanent magnets. It is, however, essential to prepare this compound in single domain particles of a grain size of the order of 10 micromillimeters. The preparation of YCo5-powders by means of the amalgam process is described in detail. The process consists of several steps, namely 1 Preparation of Y-amalgam by solving yttrium-metal at 450C in liquid mercury 2 preparation of Co-amalgam by electrolysis 3 mixing of the amalgams 4 distillation of the mercury at temperatures up to 1100C. By X-ray investigations the structure of YCo5 was confirmed and the range of homogeneity established to be very small. Metallographic and magnetic measurements proved that the amalgam process actually is a preferable means for preparing YCo5 powders. Author
