Crystallization and Densification of Nano-Size Amorphous Cordierite Powder Prepared by a PVA Solution-Polymerization Route
A homogeneous and stable amorphous‐type cordierite (2MgO2Al2O35SiO2) powder was prepared by a solution‐polymerization route employing a Pechini resin or a poly(vinyl alcohol) (PVA) solution as the polymeric carrier. After calcination at 800°C for 1 h under atmospheric conditions, the bulky precursor...

After calcination at 800°C for 1 h under atmospheric conditions, the bulky precursor changed into a very soft and porous powder. A 30 nm size, amorphous‐type cordierite powder was prepared by attrition milling the calcined powder, which was made using a PVA precursor solution.
