|Title:||XRD study of thermal stability of hydroxyl-aluminium chloride|
|Authors:||Goswamee, Rajib Lochan|
|Abstract:||An XRD study of hydroxyl - aluminium chloride has been carried out at different temperatures in a dry atmosphere. It has been observed that solid hydroxyl-aluminium chloride, obtained from an aqueous solution by drying under very mild conditions, gives an XRD pattern characteristic of a crystalline material. The transition from crystalline to semi-crystalline state at temperatures above 8OoC gives evidence of the role of coordiriated water molecules and hydroxyl groups in building up the crystalline structure at lower temperatures. SEM pictures of hydroxyl-aluminium chloride dried under mild heating show platy habits.|
