ABSTRACT:
(1) Rehydration bondable alumina of median particle size less than 5 microns, LOI (250.degree. to 1100.degree. C.) about 4 to 12% by weight, and having the ability to yield rehydration bonded objects of lower density and higher strength as compared with objects made of seven micron rehydration bondable alumina, or density less than 0.9 cm.sup.3 /g at strength about equal to or greater than 7 MPa; (2) rehydration bondable alumina having the ability to yield rehydration bonded objects having at least 0.6 cc of pore volume per gram for pores smaller than 300 Angstroms. Also encompassed are materials containing such alumina and originating from e.g. bauxite.
