WebThe behavior of tachydrite and spodumene, individually, during heating is investigated by differential thermal analysis. It was observed that tachydrite gradually loses its water of crystallization, becoming anhydrous at 573 K. Spodumene, on the other hand, is stable, showing a mass loss of 0.3 pct. around 693 K.

Webβ-spodumene. The α-spodumene is virtually refractory to hot acids. As a result of the phase transformation, the spodumene crystal structure expands by about 30% and becomes amenable to hot sulphuric acid attack. Due to this expansion, the specific gravity of the spodumene decreases from 3.1 g/cm3 (natural α-spodumene) to around 2.4 g/ WebApr 1, 2015 · The atomic arrangement presented by beta-spodumene, with a structure containing basically Al O Si bonds, restricts access to the interstitial sites occupied by lithium, making it difficult to ...
