Abstract
Disclosed in a process for forming a ceramic body from colloidal boehmite and alpha alumina. Alpha alumina is added to the colloidal boehmite to produce a seeded gal, the seeded gel capable of being sintered at a low temperature to produce a ceramic product having at least a 90% theoretical density.
