Powders of alpha alumina ultrafine nanoporosos process solution and gel preparation)

摘要

"Post alpha - alumina ultrafine nanoporosos process solution and gel preparation of the same.The present invention relates to powders of 244 - alumina comprising particles of alumina - 244 of which at least 80% of particles of 244 - alumina have a particle size of less than 100 nm.The invention also provides a fluid paste, particularly aqueous fluid pulp which comprises powder of 244 - alumina of the invention.The invention also provides methods for production of powder of 244 - alumina and folders are 244 - alumina of the invention and methods of polishing by using the same.
