摘要
The grain growing dynamics including the growing process, the growing exponent and the growing activation energy is obtained for the MgO-CaO composite ceramics with the additions of Fe2O3, CeO2 and/or ZrO2 as fluxes by measuring the size of grains with the method of Straight Line Across. The results show that all of the additions, in which Fe2O3 is the strongest, have notable effects on the grain growing dynamics by reducing the growing activation energy and promoting the grain growing. The research gives a good reference for the additions of fluxes to the matrix of ceramic filter.
