HIGHER ORDER AGGREGATE PARTICLES OF PHENOLIC RESIN FINE SPHERES, METHOD FOR PRODUCING THE SAME, HIGHER ORDER AGGREGATE PARTICLES OF CARBON FINE SPHERES

摘要

PROBLEM TO BE SOLVED: To provide higher order aggregate particles of phenolic resin fine spheres, which have an extremely small metal impurity content and not needing a grinding process.;SOLUTION: The higher order aggregate particles of phenolic resin fine spheres are characterized in that the phenolic resin fine spheres form three-dimensional structures. The phenolic resin fine spheres have an average small diameter of 0.1 to 10 micron meter, and the higher order aggregate particles have an average radius of 0.1 to 1,000 micron meter. The higher order aggregate particles are produced by polymerizing a phenol compound with an aldehyde compound in the presence of an ammonium salt such as ammonium carbonate, ammonium bicarbonate or ammonium acetate.;COPYRIGHT: (C)2008,JPO&INPIT
