ABSTRACT:
A corona discharge device having a modified barrier which improves the discharge properties, is described. The device includes a metal electrode, a low field conductive plane and an ac or dc voltage source for applying a potential to the electrode. The barrier is positioned between the electrode and the plane and, in various embodiments, is in contact with either the electrode or the plane or neither one. The barrier is comprised of any of several materials including a doped glass or ceramic, a porous glass or ceramic, a dispersion of metal with glass or ceramic, a semiconductor, a photoconductor or a fibrous material which functions as a catalyst substrate.
