Abstract

Thermal treatment and consequent dehydration modifies the structure of boehmite gel, which transits from a polymeric, partially disordered state to the crystalline α-alumina via several transition phases. We have investigated the evolution of the microstructure and structural order in the lattice. The significance of particle morphology is brought out in the sintered gel powder pellet. The transparency of the gel glass, despite the large porosity confirms the absence of long range order upto the δ-phase.
