The role of carbon presence on the strontium hexaferrite phase decomposition during pressureless spark plasma sintering (pSPS)

Open Ceramics
The phase composition and microstructure of Sr-hexaferrite (SFO) ceramics govern the hard magnetic properties. Here, pressureless spark plasma sintering (pSPS) technique was employed for the rapid consolidation (500 °C/min) of SFO in a radiating graphite
