Synthesis and characterization of ceramic refractories based on industrial wastes [PDF]

open access: yesScientific Reports
The possibility of reusing ceramic roller waste to produce cordierite and mullite refractories was investigated. Five batches were designed using wastes representing ceramic roller waste, magnesite, and silica sand, shaped and fired at 1300 °C/2 h, and ...

Microwave sintering of mullite-Al2O3 from kaolin precursor [PDF]

open access: yesMaterials Research, 2014
In the present work the effect of the microwave hybrid fast sintering of mullite-Al2O3 with non-stoichiometric mullite composition was investigated. Samples were fast sintered using a range of microwave power from 1.2 to 2.1 kW. The mullitization process
