Plasma experiments are as follows : Properties of NOx gas dynamics during a glow discharge sputtering with LaB6 cold cathode are studied experimentally. For the purpose of decomposing NOx gases, boron-compound cathode like an lanthanum … More hexaboride (LaB6) or BN is applied for the cathode material. The application of these materials for the cathode is due to the fact that the sputtered Boron is shown experimentally to be react satisfactorily with oxygen gases.6. A disk of 50mm in diameter with 5mm thick of LィイD2aィエD2BィイD26ィエD2 is arranged perpendicularly to the cylindrical anode. The anode has a diameter of 100 mm and is 300 mm in length. In the chamber, an electro-static probe for measurement of the electron density and plasma potential is arranged. The small sample tip for x-ray photoelectron spectroscopy (XPS) measurement is also installed near the cathode electrode. Dynamics of partial pressures of residual gases are measured by using a quadruple mass analyzer (QMA) during and after the discharge. The experiment show that the glow plasma by using LaB6 electrodes is apparently effective to decompose NOx gases during the sputter discharge.7.
