Nanosized corundum synthesis

摘要

Alumina continues to play an important role in the materials industry with the Bayer process still pro- viding alumina after a 100 years of continuous process- ing. In addition to traditional applications of alumina, alumina is being advanced as a major part of the new frontier on nanophase materials and nanophase technolo- gy. High surface area corundum has been synthesized us- ing a rapid totally "green" hydrothermal process for forming nanosized diaspore precursor to nanosized co- rundum. Surface areas of the nanosized corundum are in excess of 160 square meters per gram.
