IONIZER

摘要

Disclosed is an ionizer that is suitable for use, for example, in clean rooms and generates little or no dust. The ionizer comprises at least one discharge electrode for applying a high voltage to air to ionize the air and thus to generate ions and a power supply part for supplying electric power to the discharge electrode. The ionizer is characterized in that at least a part of the discharge electrode is formed of an electroconductive vanadate glass obtained by a process in which an electroconductive vanadate glass obtained by preparing a mixture containing a vanadate, then melting the mixture and rapidly cooling the mixture, or an electroconductive vanadate glass obtained by further annealing the glass is immersed in an aqueous liquid medium.
