Studies on chemical preparation of Fe-P-B ultrafine amorphous alloy particles and the interaction of the components

A series of Fe-P-B ultrafine amorphous alloy power samples, which can be expressed approximately as Fe-82 PxB18-x (2.4 less than or equal to x less than or equal to 10.1), have been chemically prepared. As the reaction temperature was raised from -7 degrees C to 28 degrees C, the P contents decreased gradually from 10.1% to 2.4% while the B contents increased gradually from 8.7% to 13.1%, Mossbauer experimental results indicates that there is a preferential bonding of Fe-P to Fe-B in the samples.
