Abstract

Homogeneous and stable amorphous-type yttrium aluminum garnet (YAG) and cordierite powders were prepared by a solution-polymerization route, employing PVA solution as a polymeric carrier. Porous and soft powders were obtained after calcination of aerated precursors. The calcined powder showed a very low residual carbon content and a high powder yield. In the case of the preparation of cordierite powder, nano-size particles, with a high specific surface area of 181 m2/g, were obtained by attrition-milling for less than 1 h. The properties of PVA, which acted in an easy burnout and steric entrapment mechanism due to its large chain molecules, made it very effective as a polymeric carrier for powder preparation via a solution-polymerization route.
