Volume 6 Issue 6, Pages 702 – 716 Kevin PlucknettPublished Online: Nov 5 2008 3:08PM DOI: 10.1111/j.1744-7402.2008.02309.x ABSTRACT Porous silicon nitride (Si3N4) ceramics have been sintered in a conventional air atmosphere furnace at temperatures between 1500°C and 1700°C, with sintering additions of either 5 or 10 wt% yttria (Y2O3). The use of a protective α-Si3N4 powder…
