✦ Synopsis

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

Carbonaceous gel beads were prepared by addition of polymers using ammonia water of amphiphilic carbonaceous material through water-in-oil emulsion. By addition of poly(vinylalcohol), carbonaceous gel beads having dimples were obtained, where the number and size of dimples were dependent on the addi
