【 摘 要 】
This paper investigates the breakdown voltage of Carbon ionised affected by butane and air gas impurities at slightly atmospheric pressure. The ionization process is conducted by electrical discharge using graphite electrode with the gap in millimeter scale to generate plasma by the direct current voltage less than 3.5kV. The experimental results show the breakdown voltage and current of plasma. Carbon plasma density and temperature are calculated from the current and voltage. These results show the ionization of air at slightly low pressure having a maximum voltage of 570V. The breakdown voltage and current are respectively 530-570V and 0.27 to 0.45mA. At high pressure it has a maximum voltage of 1160 V, the voltage and the current breakdown are respectively 900-1100V and 0.46 to 0.6 mA. When gas impurities are injected at slightly low pressure, it has maximum voltage of 772V, the breakdown voltage is 536-775V and the current is 0.03 to 0.45mA, whereas at high pressure it has a maximum voltage of 1044V, the breakdown voltage is 675-105 V and the current is 0.03 to 0.69mA. The results are interesting phenomena and can also be applied to develop a level of purity of Carbon Nano Tube formation at the cathode end of the effects of the density and temperature of the plasma generated.
