| Description | Barium hexaferrite ceramic permanent magnets were manufactured using a locally produced iron oxide. The effect of sintering temperature on the coercivity, remanence, shape of the hysteresis loops, density and shrinkage was studied. The results indicated that grain growth during the sintering process limited the sintering temperature to 1 200 °C for this material in order to obtain satisfactory values for the coercivity, while remanence and density were optimum at a higher sintering temperature of about 1 230 °C. ’n Plaaslik geproduseerde ysteroksied is gebruik om permanente magnete van bariumheksaferriet keramiek permanente magnete te vervaardig. Die effek van sintertemperatuur op die koërsiewe krag, remanensie, vorm van die histereselus, digtheid en krimping is bestudeer. Daar is bevind dat korrelgroei tydens die sinterproses die koërsiewe krag sodanig verlaag dat die maksimum sintertemperatuur beperk is tot 1 200 °C vir hierdie besondere materiaal, terwyl ’n geskikte temperatuur vanuit die oogpunt van remanensie en digtheid ongeveer 1 230 °C is. | |
