Title:
磁性グラファイト材料を調製する方法および磁性グラファイト材料
Document Type and Number:
Japanese Patent JP4996459
Kind Code:
B2
Abstract:
A process of preparing magnetic graphitic materials from graphite in a second container (3) that reacts with one of more transition metal oxide and in a first container (2) at a volume ratio of 1:1, in a closed reactor (1), heated up to a temperature between 600° C. and the melting temperature of the transition oxide (s) for 6 to 36 hours, under a pressure of 10 atmospheres with the help of a transfer inert gas through an inlet (5) and vacuum between 10−2 torr to 10−7 torr through an outlet (6), obtaining at the end of the process a graphitic material with long-lasting magnetic properties at room temperature. The material obtained exhibits a complex structure, with pores, bunches, pilings and edges of exposed graphenes and finds application in nanotechnology, magnetic images in medical science, applications in communication, electronics, sensors, even biosensors, catalysis or separation of magnetic materials.
