Weight losses from zinc ferrite and nickel ferrite during sintering
- 82 Downloads
The sintering in air of fully formed zinc ferrite and nickel ferrite is always accompanied by a loss of weight from the ferrite, caused by removal of some oxygen. Although the rate of weight loss from the ferrite has the same time and temperature dependence as the rate of shrinkage of the specimens, it is found that altering the loss of weight by changing the oxygen pressure has little effect on the sintering of fully formed ferrites. Criteria are established for the preparation of high density and high resistivity sintered ferrites.
