Abstract:
|
Optimum conditions for the preparation of tape recording quality
Y-Fe20 s by the thermal decomposition of ferrous oxalate dihydrate have been established.
Formation of the intermediate F%O~ which is most important in forming
Y-FezO 3 takes place only in the presence of water vapour. Various stages of
decomposition have been characterised by DTA, TG, DTG, and x-ray powder
diffraction. The method for the preparation of acicular "Y-Fe208 that matches
very well with the commercial tape recording material has been developed |
