Magnetic bone cement is a novel magnetic medium that generates heat under alternating fileds for bone tumor treatment as well as recovery of bone fracture. Seven kinds of metal microspheres were chosen to test their heat-generating abilities and magnetic properties. The selected materials were then mixed with calcium phosphate bone cements (CPC) at different powder liquid ratios. The setting time, mechanical tests, magnetic properties, and heat-generating abilities of the cement were analyzed. The results showed that the novel CPC-based magnetic bone cement had satisfactory heat-generating ability, which could be further applied for magnetic hyperthermia clinically.
