Studies on the sintering of tricalcium aluminate

Abstract

Sintering studies were carried out on tricalcium aluminate prepared by solid-solid reaction between calcium carbonate and aluminium oxide. Effects of forming pressure, particle size, sintering temperature and sintering time were investigated. The data were analysed using the empirical equation D = K log t+C. It was observed that the activation energy for the later stage of sintering increases with particle size from-55+45/j.μ to-75+ 63μ. Increase in compaction pressure, sintering temperature and use of multisized particles gave nearly theoretical density. © 1975 Taylor and Francis Group, LLC.
