Using porcelain insulation for glow discharge plasma of the DC planar reactor

Resumo

In this work we built the electric insulation with porcelain material to encapsulate the electrodes of a planar reactor properly to generate a normal electrical glow discharge betweeb the cathode and anode electrode with DC power supply. During luminescent plasma discharges was possible identify electron column region. For keeping the stability of plasma was evaluated a sensible parameters conditions like as gas argon pressure and also breakdown voltage. During measument of a range of pressure versus electric tension was possible study the states of the stability condition of the plasma and plot Paschen's Curves with minimum sparking potential [1]. Breakdown voltage Vb is the minimal electric voltage that keeps DC glow discharge with maximum ionization, at point (pd)min, of the product pd of the pressure of gas argon times the gap between electrodes.
