A method for producing ozone-water includes steps of providing a cathode and an anode so as to interpose a solid polymer film therebetween, and electrolyzing water. A conductive diamond having one of a porous structure and a mesh structure is used as the anode. Ozone-water of an intermediate to high temperature is produced by electrolyzing water of an intermediate to high temperature.

An ozone generating apparatus is provided which includes a pair of electrodes for producing a discharge by the application of an ac voltage therebetween, and at least one dielectric provided between the pair of electrodes. A source gas containing oxygen is provided into a discharge space in which the discharge is produced to generate ozone by the action of the discharge. A surface lying between at least one of the pair of electrodes and the discharge space and in contact with the discharge has a surface resistivity of 104Ω to 1011Ω. The source gas provided into the discharge space includes ultrapure oxygen having a purity of not less than 99.9%.

A silent discharge plasma apparatus includes a dielectric member, a pair of electrodes opposed to each other across the dielectric member and an alternating-current source applying an alternating-current voltage between the electrodes and causing a discharge. A gas is supplied to a discharge space, where discharge occurs, and a plasma is produced. At least one of the electrodes includes a conductive power feeding thin film on the dielectric member. When the dielectric member is destroyed and an arc discharge develops between the electrodes, the power feeding thin film is eliminated or oxidized, and the arc discharge is stopped.

Decrease in the ozone concentration that becomes a problem when high purity oxygen is used as a raw material gas is prevented. A high purity alumina substrate having a high screen degree is used as a dielectric. A catalytic substance to hinder the decrease of the ozone concentration is fixed on the surface of the alumina substrate as the dielectric by a baking fixing agent. The baking fixing agent is a glass that becomes a paste form that is capable of powder kneading the catalytic substance and attaching to the surface of the dielectric, fixes the catalytic substance on the surface of the dielectric by hardening by baking, and shows ozone resistance and sputtering resistance under the production of ozone in the discharge gap, and forms a functional film containing a large amount of the catalytic substance and is stable on the surface of the dielectric.

The present invention relates to a method for metal coating on a tube, particularly a tube for ozone generators which have been widely used for commercial and industrial purposes. Quartz or high aluminum-oxide-containing is a preferred material for the tube for an ozone generator. According to the present method, the tube is coated with a film of gold by putting the tube in a stove wherein the temperature and baking time is controlled. The present method for coating improves the durability of tubes operated at high temperature brought forth by micro-discharge, and thus extends the service life of the tube as used in an ozone generator.
