Abstract
Carbon microbeads were prepared from water-in-oil emulsion using amphi philic carbonaceous material and urea. With urea as a forming agent wi th a concentration 1-20 wt.%, hollow carbon-microbeads were obtained, and their particle size ranged between 2 and 15 mu m. The true density of the hollow carbon-microbeads was changed, by varying the concentra tion of urea and the heat-treatment temperature. In particular, a pore size of about 50 Angstrom was predominantly produced under a certain condition.
