Pressureless reaction sintering of YAG was carried out by using a precursor powder in the hydroxyhydrogel form synthesized by flash polycondensation technique. Reactive silica additive was used to modify Al-O-Y network where Si(4+) was incorporated in the solvated form. The sintering experiments were carried out with the processed powder up to 1650 degrees C under ambient ambience. Densification indicated effective sintering with well-formed microstructure. Phase identification by XRD indicated only YAG in the sintered specimen. (C) 2011 Elsevier Ltd and Techna Group Sri. All rights reserved.
