Study on the Composite Strengthening Effect of Talc and Kyanite Addition on Corundum–Mullite Based Ceramic Foam

Abstract:

Article Preview

Corundum–mullite based ceramic foams were prepared by adopting foam impregnation process with raw talc and kyanite as modifiers. By comparing the sinters strength among the original formula with and without talc and kyanite added, it can be seen that when 6wt% raw talc was added, the compressive and flexural strength of the sintered foam ceramic bodies are increased by 108.9% and 33% respectively more than the original formula. Adding 4wt% ball-milled kyanite on this basis, the compressive and flexural strength were further elevated 20.1% and 29.1%, respectively, and meanwhile, the sintering shrinkage rate was dropped by 54.2%.
