Preparation of Ultra Fine Alumina Powder Via Ammonium Aluminium Carbonate Hydroxide
AACH 를 이용한 고순도 알루미나 분말 제조
Abstract
The ultra fine gamma-alumina powder was prepared via ammonium aluminium carbonate hydroxide (AACH). The XRD, SEM, BET, thermal analysis were used to characterize the samples. The effects of various reaction parameters as concentration, of solution, anion on specific area, PH, aging time and thermal decomposition condition on the produced AACH and alumina were discussed.
