MICROCARBON ROD AND ITS PRODUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a microcarbon rod wherein a micro material is chemically adsorbed and retained on a surface, and a mechanical measurement can be carried out. SOLUTION: Graphite fine powder of an average grain size of 1 μm is mixed with an organic matter in which a glassy carbon of retardant graphitization remains after sintering a chlorinated vinyl chloride resin or the like, then it is sintered after extrusion with a dies of 50 μm in diameter to produce the microcarbon rod comprising a glassy carbon and a crystalline carbon.
