Title:
The manufacturing method of alumina hydrate particulate powder, and alumina hydrate particulate powder
Document Type and Number:
Japanese Patent JP6052780
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for preparing alumina hydrate fine particle powder which exhibits excellent dispersibility to water, the dispersion liquid of which has excellent stability, and which can be used suitably as a binding material, a raw material of catalysts or catalytic carriers, or the like.SOLUTION: The method for preparing alumina hydrate fine particle powder comprises: a step (a) of preparing an alumina hydrate gel and cleaning the prepared gel; a step (b) of adding a buffering agent and a deflocculant to alumina hydrate fine particles so that the alumina hydrate fine particle becomes 100 parts weight in terms of AlO, the buffering agent becomes 5-15 parts weight, and the deflocculant becomes 5-30 parts weight and aging an obtained mixture; and a step (c) of spray-drying the aged mixture.
