Grain-boundary R oxycarbide raises ThMn12 rare earth magnet density to 7.3 g/cm3 or more, helping stabilize magnetic characteristics over time.
Controlled dopant addition before curing and pyrolysis produces 99.99%–99.9999% pure SiC and SiOC while simplifying purification.
Boron substitution reduces strain energy in carbon clathrates, enabling high-pressure synthesis and recovery to ambient conditions.
