Daftar Isi:
- Measurement of electrical properties of graphite materials as the mechanical treatment result with high energy milling (HEM) techniques was carried out. The carbon powder was milled using HEM by varying the milling time from 25 hours to 100 hours, and afterwards the graphite material was formed to a pellet under compaction up to 20 ton/cm2. The measurements result of electrical properties using LCR (Inductance, Capacitance, Resistance) meter showed that milling process to graphite causes the increasing of conductivity and capacitance values and these values were increasing with the increase of milling times. Before milling, the conductivity value is 3.5976 Siemens/cm and the value of capacitance is 0.2223 μF at 100 kHz frequence. Increasing of conductivity value reached 26% and capacitance value reached 66% after milling for 100 hours. These incresing are analized due to decreasing of graphite powder particle size causing by longer milling time and result in higher electrical conductivity.Keywords: Mechanical Treatment Graphite, Electrical Properties, Conductivity, High Energy Milling.
