Abstract
A solid insulator having high electrical resistance of inorganic and organic materials such as ceramic, glass, plastics, resins which is treated by application of an ion beam to the insulator surface to effect incorporation by controlled implantation of ions in the insulator adjacent its surface to produce an insulator surface of desired conductivity. This overcomes the difficulties due to uneven voltage distributions on the insulator surface which can cause discharges and even the destruction of the insulator.
