  • Method for manufacture of sintered alumina from ammonium aluminum carbonate hydroxide
    Patent number: 4053579
    Abstract: Aluminum carbonate hydroxide ammonium, a new compound, is produced by causing a solution of ammonium hydrogencarbonate to be reacted upon by a soluble aluminum salt. .alpha.-Alumina is obtained by thermal decomposition of this ammonium aluminum carbonate hydroxide. By sintering said .alpha.-alumina, there is obtained sintered .alpha.-alumina.
