Abstract

This invention relates to method for enabling alumina have high specific surface after treatment at high temperature, the method comprising preparing alumino-calcium compositions by coprecipitation technique; calcining the alumino-calcium compositions; immersing the alumino-calcium compositions in acid liquid for acid treatment; setting working temperature lower than the boiling point of the acid liquid, whereby alumina with high specific surface is obtained.
