Barium hexaferrite ceramic permanent magnets
Suid-Afrikaanse Tydskrif vir Natuurwetenskap en Tegnologie, 1983 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 ...

Triple‐Stimuli Responsive Soft Robots with Photo‐Programmable Ferriferous Oxide Particle Patterns
Advanced Science, Volume 12, Issue 18, May 15, 2025.The in situ generation of Fe3O4 nanoparticles in polymer substrate is realized by combining photo‐reduction of Fe3+ to Fe2+ and hydrolytic reaction of the two ions. By spatiotemporal control of UV light irradiation, the distribution of Fe3O4 nanoparticle can be well controlled, which enables the composite with magnetic field, NIR light, and moisture ...
