Title:
AMORPHOUS CARBON PARTICLE AND COMPOSITE MATERIAL CONTAINING THE SAME
Document Type and Number:
WIPO Patent Application WO/2005/077825
Kind Code:
A1
Abstract:
Amorphous carbon particles extracted from petroleum coke combustion ash, characterized in that the particles each have a non-circular section, exhibiting a weight reduction, measured after heating at a constant temperature of 500°C in the presence of air for 60 min, of less than 30% and have an average particle diameter of 50 to 1 μm. There is further provided a composite material characterized in that the amorphous carbon particles are mixed in a matrix of organic material or inorganic material. Thus, it becomes feasible to obtain with economic efficiency amorphous carbon particles excelling in rigidity and strength and having extremely small specific surface area and pore volume and to provide a composite material whose performance has been improved by incorporation of the amorphous carbon.
