[ 1 ] - Grain growth kinetic of spark plasma sintered magnesia

In this research, the densification of magnesia nanopowder with a mean particle size of about 100 nm was investigated by spark plasma sintering undera pressures of 80 MPa and at temperature range from 1000 °C to 1400 °C and a heating rate of 50 °C/min for 20 minutes. The density of the samples slowly increased with increasing sintering temperatures to 1200 °C. Afterwards, with more increasing o...
