Preparation ultra fine particles from Ceramic refractorymaterial using CO2 Laser


Samples of compact magnesia and alumina were evaporated using CO2-laser .The
Processed powders were characterized by electron microscopy and both scanning and transmission electron microscope. The results indicated that the particle size for both powders have reduced largely to 0.003 nm and 0.07 nm for MgO and Al2O3, with increasing in shape sphericity
