Aluminum product and its method of preparation

Claim 1

A PROCESS FOR PRODUCING ALUMINA COMPRISING SLOWLY ADDING IN INCREMENTS AND WITH STIRRING AN AQUEOUS ACIDIC SOLUTION OF AN ALUMINUJ SALT WHOSE ANION IS REMOVABLE FROM SAID ALUMINA TO A SUBSTANTIALLY ALKALI METAL-FREE AQUEOUS AMMONIUM HYDROXIDE SOLUTION, MAINTAINING THE PH OF THE AMMONIUM HYDDROXIDE SOLUTION AT A VALUE ABOVE 7 THROUGHOUT THE ADDITION OF ACIDIC ALUMINUM SALT SOLUTION, SUBSTANTIALLY AVOIDING EVEN LOCALIZED ZONES IN SAID AMMONIUM HYDROXIDE SOLUTION BELOW A PH OF 7 DURING THE ADDITION OF ACIDIC ALUMINUM SALT SOLUTION, PRECIPITAINING A CRYSTALLINE ALUMINA HYDRATE CONTAINING BETWEEN 1.2 AND 2.6 MOLES OF WATER OF HYDRATION PER MOLE OF AL2O3, SAID ALUMINA HYDRATE BEING UNSTABLE AND TENDING TO TRANSFORM INTO A DIFFERENT HYDRATE OF ALUMINA, PREVENTING SAID TRANSFORMATION BY MAINTAINING SAID ALUMINA HYDRATE PRECIPATE AT A TEMPERATURE ABOVE ABOUT 170*F. THROUGHOUT THE MIXING OPERATION AND SUBSTANTIALLY AS LONG AS IT IS IN THE WET STATE, CONTINUOUSY MAINTAINING AMMONIA SATURATION IN THE MIXED SOLUTION SUFFICIENT TO SUBSTANTIALLY AVOID EVEN LOCALIZED ZONES BELOW A PH OF 7, SEPARATING SAID ALUMINA HYDRATE FROM SUPERNATANT LIQUID AND DRYING SAID ALUMINA HYDRATE.
