Popis:	The natural diaspore from Jhansi, India was ground in a pot mill in different conditions (dry and wet). The wet grinding was carried out in different media (acidic, basic and neutral) and with deflocculated aqueous diaspore suspension (60 wt%). The sodium polymethacrylate salt (mol. wt. 1200 g.mol−1) was used as the dispersant. The range of particle size of diaspore at which a limit of the grindability exists was also investigated. The effect of grinding on the thermal behaviour of dehydration and α-transformation was examined by means of differential thermal analysis (DTA), thermogravimetry (TG) techniques.
