ALUMINA PARTICLE AND METHOD OF MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide plate-like primary particles of alumina which are free from flocculation and has a high aspect ratio. SOLUTION: The plate-like primary particles of alumina are obtained by crushing secondary particles formed by flocculation of plate-like primary particles of alumina and each has no crushed face. Crushing of the secondary particles is carried out while suppressing crushing of the primary particle by using an air flow-type crusher. COPYRIGHT: (C)2004,JPO
