Analisis Ionisasi Plasma Karbon Gas Butana Pada Plasma Termal

---

Production of carbon plasma at atmospheric pressure can be applied to form a Carbon Nanotube (CNT). CNT formation is experimentally generated and produced in a chamber. This process uses the electrode gap (±1 mm) of the pencil graphite electrodes to generate the plasma by electrical-discharge method. This process is done by ionising the gas at various pressure. Carbon plasma was produced by operating direct current voltage (DC) of < 3kV and flowing Butane gas into the chamber tube where air and Butane ratio levels were taken into account. Variations of pressure are applied to study the process of ionization that occurs inside the tube. The experimental results showed a breakdown voltage and the current generated by various pressure. The electrical measurement are voltage, current, both before and after ionization. The density and temperature of plasma carbon are calculated. The result show that the ionization of air at low pressure has maximum voltage is 570 V, the breakdown voltage is 530-570 V and the electrical current is 0,27-0,45 mA, while at high pressure have maximum voltage 1160 Volt, the breakdown voltage is 900-1100 V and the electrical current is 0,46-0,6 mA. Ionization occurs readly while added a Butane at low pressure has the maximum voltage is 772 V, the breakdown voltage is 536-775 V and the electrical current is 0,03-0,45 mA. Meanwhile at high pressure, the maximum voltage is 1044 V, the breakdown voltage is 675-1055 V and the electrical current is 0,03-0,69 mA. These results are in accordance with the variation of the gas inside the tube. This report has shown good results to potentially develop CNT growth at the end of the cathode.
