Abstract

The general composition for an α′-sialon is M_x(Si, Al)₁₂(O, N)₁₆, (the value of x lies between 0 and 2), where M is a modifying cation such as Li⁺, Ca²⁺, Y³⁺ or a number of the lanthanide cations (Ln³⁺). This paper reports extended X-ray absorption fine structure (EXAFS) spectroscopy measurements of a hot-pressed erbium containing α′-sialon, using the synchrotron radiation source at Daresbury, UK. This technique provides short-range structural information within this engineering ceramic. The results suggest that the erbium modifying cation shows a preference for being located in one particular site within the ceramic network.
