Influence of Grinding in Pyrophyllite−Mullite Thermal ...
The influence of grinding on the thermal transformation of pyrophyllite to mullite is analyzed by 27 Al and 29 Si MAS NMR spectroscopies, using X-ray powder diffraction and thermal analysis (DTA-TG) as complementary techniques. Mechanical treatments by dry grinding produce partial destruction of pyrophyllite and rearrangement of Al ions in tetra- and pentahedral environments.
