Interaction dynamic «solid state-liquid» in the process of aluminum hydroxide termotreatment in distilled water

Interactions «solid state - liquid» have been researched in the process of technical aluminum hydroxide thermal treatment in distilled water while the solutions have periodically been changed. The dissolution of gibbsite crystals during thermal treatment in distilled water at temperature range 20-90°C has been described on the basis of experimental results. Higher solubility of gibbsite crystals, compared to literature data, has been observed due to the alkaline impurities in their structure.
