| ABSTRACT |
|
Mn-Zn ferrite powders prepared by an alcoholic dehydration method. Vacuum casting, a kind of wet forming process was examined with this powders. As binders, polyethylene glycol and polyvinyl alcohol were used. In order to estimate this conditions, fracture morphology, densities of green and sintered bodies and the microstructure were observed. High density and homogeneous microstructure in sintered bodies were obtained in the case of 0.1 wt% PEG or 0.5 wt% PVA. |
