A. Bianco et al., PREPARATION OF NI-CO METAL POWDERS BY CO-REDUCTION OF NI(II) AND CO(II) HYDROXIDES FOR MAGNETORESISTIVE SENSORS, Materials letters, 19(5-6), 1994, pp. 263-268
The preparation of Ni-Co powder for magnetoresistive sensors was studi
ed. A submicron Ni-Co powder was obtained in good yield by reduction o
f freshly prepared Ni(II) and Co(II) hydroxides in ethylene glycol. Th
e product was a chemically homogeneous powder alloy with a fcc lattice
and a Ni/Co atomic ratio of 70/30. The morphology and the composition
of the solid solution are the most suitable for the preparation of th
ick films for physical sensors.
