In the present work, multi‐cation‐doped (Sr 2+ –Mg 2+ ) SiAlON ceramics were investigated. MgO and SrO were used in 100:0 and 50:50 molar ratios. The mixture was sintered at 1800° and 1830°C for 1 h in a gas pressure‐sintering furnace. The results showed that sintered samples were composed of mainly α‐ and β‐SiAlON phases and small amounts of some Sr‐containing phases and SiAlON polytypes. According to Rietveld analysis of X‐ray diffraction patterns, Mg is incorporated into the α‐SiAlON structure. However, the incorporation of Sr is limited.
