Applications of Comminution Techniques for the Surface Modification of Powder Materials.

Abstract

This paper reviews a new method for surface modification to cover particle surface with fine particles mechanically in a dry phase by making use of comminution techniques.First, the relation of comminution process with surface modification technology is discussed, and the advancedmachinesdeveloped in Japan to treat core particles surface with fine particles based on grinding principles are introduced. Then, the details of the composite process of core/fine particles with these machines are explained.In the second section, the effects of the controlling factors on the composite process such as mechanical actions, treating temperature and atmosphere are discussed.The

Effects of Surface Processing of Lactose Carrier Particles on Dry Powder Inhalation Properties of Salbutamol Sulfate

“…Naito et al reported that composite particle fabrication using a Mechanofusion system results in a decrease in the specific surface area of processed particles, compared with that of unprocessed particles. 21) In this study, after application of intermittent shear stress to lactose particles using a ThetaComposer ® , the specific surface area of surface-processed lactose decreased. The mechanism of this decrease may be as follows.…”

Fabrication of ZnO ceramics using ZnO/Al2O3 nanocomposite particles prepared by mechanical treatment

“…By using this mechanical treatment process, we can obtain nanocomposite particles; in this process, nanoparticles are bonded to submicron particles by applying an external mechanical force, especially shear force. 10) For example, we have reported the direct bonding of TiO2 particles to Si3N4 particle by mechanical treatment, and it is possible to fabricate nanoparticle-dispersed Si3N4 ceramics.…”

Development of Advanced Ceramics by Powder Composite Process

“…We have focused on the fabrication of advanced ceramics by using a powder composite process in which nanopar ticles are mechanically mixed using only a dry mixing process, which allows us to obtain nanocomposite particles. In this process, nanoparticles are bonded to submicron particles by applying an external mechanical force, specifically a shear force 1,2) . Many types of powder composite processes have been developed commercially 1,2) .…”

“…In this process, nanoparticles are bonded to submicron particles by applying an external mechanical force, specifically a shear force 1,2) . Many types of powder composite processes have been developed commercially 1,2) . These nanocomposite particle processes are divided into two types: the bonding of fine particles to a core particle and the homogeneous mixing of various fine particles.…”
