ABSTRACT:
The process of the present invention resides in the production of an extremely pure basic aluminum-sodium carbonate of the dawsonite type. In the process of the present invention, aluminum hydroxide is reacted with an aqueous sodium bi-carbonate solution at a temperature between 160.degree. and 240.degree. C. and at a pressure of 5-50 atm. The reagents from an aqueous suspension which is stirred throughout the duration of the reaction and the temperature of the reaction is chosen in accordance with the length of crystalline fiber which is to be produced.
