| ABSTRACT |
|
Ni0.3Zn0.7Fe2O4 ferrite specimens were fabricated by dry pressing and tape casting method. The properties of each specimen were measured and compared. In order to design and manufacture the chip devices effectively, one important criterion can be that the sintered density of the laminated body should approach close to that of the dry pressed body which is regarded as standard. This requirement could be satisfied by controlling the solid loading of the ferrite sheet, lamination temperature and pressure. Using the optimum conditions (solid loading 55 wt%, lamination temperature 6$0^{circ}C$, lamination pressure 400 kg/$textrm{cm}^2$, sintered at 125$0^{circ}C$ 2h) a sintered ferrite, with the density of 5.18g/㎤ and permeability of 1390 at 0.5 MHz, were obtained. |
