Abstract: With more and more heated competition and often decreasingprice in international alumina market, both metallurgical and non-metallurgical industry is having a strict demand on physical and chemical char-acter of alumina. Therefore, it is very important to measure its particle sizeand specific surface, observe its morphology during alumina production.Through studying and quantifying above-mentioned characters, a variouskinds of sandy,ultrafine and highwhiteness hydrate alumina are produced.

Key words: hydrate alumina; particle size; specific surface area
