Physicochemical and structural characteristics of nano eggshell

Nano eggshell calcium (NEC) powder was prepared from biowaste chicken eggshells using wet ball milling. The characteristics of the NEC, including the zeta potential, micromorphology, elemental composition, particle size distribution, Ca 2+ concentration, and chemical structure, were investigated. According to the results, the optimum process CNTs/Cu composite powders were prepared by an electroless plating and planetary ball milling process. The structure of composite powders was investigated. Results showed that Cu particles are homogeneously deposited on CNTs surface, and CNTs are deeply embedded into Cu matrix after milling, which play an important role in An electroless plating and planetary ball milling process for

Ball Milling method for synthesis of nanomaterials

I have seen an interesting image at for ball milling method at wikipedia. You can see the image here. Advantages of ball milling process: 1. Nanopowders of 2 to 20 nm in size can be produced. The size of nanopowder also depends upon the speed of the rotation of the balls. 2. It is an inexpensive and easy process. Disadvantages; 1. As theIn the literature, porous copper product was also synthesized by ball milling and surface oxidation [12]. Ball milling is a noble process of grain refinement and phase formation in solid state due to repeated cold welding, fracturing and re-welding of the powder particles which are fed between the impact of one ball to another and the wall of Effect of milling time on powder characteristics and mechanical
