Abstract (en)
[origin: US4841409A] A corona discharge electrode has a core made of a malleable, at least partially electrically conductive graphite material. The core is coated by a relatively thin layer of a dielectric material of an oxide free ceramic such as silicon nitrite, boron nitrite or aluminum nitrite. The density of the dielectric layer is at least 95% of the theoretically attainable density.
