Properties of In Situ Synthesized Alumina Ceramic Core Composites
A series of alumina-based ceramic cores were in situ prepared. Effect of kyanite on the properties of ceramic core was discussed. The results indicated that the microstructure of the core is characterized by the presence of unreacted Al2O3 particles having a polycrystalline composition consisting essentially of in-situ synthesized 3Al2O3 .2SiO2 on the surface of the Al2O3 particles. The ceramic cores of kyanite contents sintered at 1500oC for 3 h have almost no creep deformation.
