Abstract
Elastic and ultra-lightweight hollow carbon fine particles and a method for producing such hollow carbon fine particles are to be provided. In the method, fine droplets are formed from a mixed solution containing a water soluble organic substance and lithium carbonate; composite fine particles of the water soluble organic substance and the lithium carbonate are prepared by drying the fine droplets formed from the mixed solution; and the composite fine particles are decomposed at a temperature in a range of 500° C. to 900° C.
