Sr2+ - Mn4+ Doped SiAION Ceramics

Abstract:

In the present work, multi-cation doped (Sr2+-Mn4+) SiAlON ceramics were investigated. The mixture was sintered at in a gas pressure sintering furnace (GPS). XRD results showed that sintered samples were composed of β and α-SiAlON phases and this result is also confirmed by back scattered SEM images. EDX analysis of the individual α-SiAlON grains showed that Mn can incorporate into the α-SiAlON structure when it is codoped with Sr.
