✦ Synopsis
Polymethylmethacrylate-based cements containing magnetite (Fe 3 O 4 ) particles were prepared and their structure and properties were investigated. The Fe 3 O 4 particles were uniformly dispersed in the cement matrix and constituted a maximum of 60 wt.% of the total weight of cement. The setting time of the cement increased and the maximum temperature during the setting reaction decreased with increasing Fe 3 O 4 content. The compressive strength of cement increased with increasing Fe 3 O 4 content. Cement with 50 wt.% Fe 3 O 4 particles generated heat in alternating magnetic fields of 300 and 120 Oe at a frequency of 100 kHz.
