A synthetic gibbsite (Al(OH)3) produced by the Bayer process was mechanically activated by attrition milling for 24 h with various grinding ball-to-powder ratios (BPR = 5, 10 and 20). Changes in its structure were studied by thermal analysis and X-ra

Publikováno v: Journal of the European Ceramic Society. 34:1409-1421

Mullite formation from kaolinite was studied by means of high-temperature in situ powder neutron diffraction by heating from room temperature up to 1370 °C. Neutron diffractometry under this non-isothermal conditions is suitable for studying high-te
