The processing of kaolin powder compact

Powder processing is crucial to the final properties of porcelain bodies. In the present study, a kaolin powder was used as the starting material, water or organic solvent was employed as the milling medium, and subsequently dried and formed by the die-pressing technique. The final phase, mullite, is obtained by sintering kaolin powder compacts. By using an organic solvent instead of water, the density, microstructure and mechanical properties show a better performance due to the avoidance of agglomerates formation.
