| description | In this paper are investigated microstructural, phase, physical and
mechanical properties of mullite ceramics obtained from clay and Bayer
electrofilter fines. Clay and alumina were mixed in such ratio that provides
the amount of AlO23 and SiO2 corresponding composition of mullite. One
mixture was manually mixed and other was milled three hours in ceramic mill.
After isostatic molding and heat treating at 1580°C and 1635°C XRD analysis
revealed approximately 60% of mullite and 40% of corundum in first mixture
and in second mixture 70% of mullite and 30% of corundum. Two types of
mullite were observed in SEM micrographs beside corundum grains and glassy
phase. The results of investigation indicate that preparation of mullite
ceramics from these raw materials is possible, if clay and alumina are well
homogenized and milled before molding. |
