Abstract:
Disclosed is a method of encapsulating soluble or colloid solids in. alpha. -alumina by forming a solution or colloid of the solids in a liquid which has a surface tension low enough to wet a non-particulate transition alumina which has a porosity of at least 40%. The solution or colloid is permitted to impregnate the pores of the alumina and the liquid is evaporated. The alumina is then heated to its. alpha. -Al. sub. 2 O. sub. 3 transformation temperature to entrap waste in its matrix and seal the pores. After the alumina has cooled, the surface of the alumina can be washed to remove any solids which were not trapped in the pores.
