Is the ozone generator corrosive to metal and non-metal materials?

As an important air purification device, the ozone generator has been widely used in many fields. However, the strong oxidizing properties of ozone have also aroused people's concern about its possible corrosiveness. In particular, when the ozone generator is working, whether the ozone gas released will corrode the metal and non-metal materials it contacts is a question we need to explore in depth.
Ozone has a strong oxidizing property, which enables it to react chemically with a variety of substances quickly. In terms of metals, ozone has an oxidizing and corrosive effect on almost all metals, except for gold and platinum, which are two metals with extremely stable chemical properties. Common metals such as iron, aluminum, zinc, and lead will be strongly oxidized after contact with ozone, causing corrosion on the metal surface. However, chromium-iron alloys, especially stainless steel containing 25% Cr, have strong corrosion resistance to ozone, so they are often used to manufacture ozone generating equipment and its parts that are in direct contact with ozone.
For non-metallic materials, ozone also shows a strong corrosive effect. For example, plastic materials such as polyvinyl chloride (PVC) are easily oxidized in an ozone environment, causing the material to become loose, cracked, or even perforated. Therefore, in the process application of the ozone generator, including production, metering, mixing, transportation, and other links, as well as the instruments and items at the site of action, ordinary rubber cannot be used as a sealing material. Instead, silicone rubber or antioxidant materials with strong corrosion resistance should be used as a substitute to ensure the stability and safety of the equipment.
The corrosiveness of ozone to metal and non-metallic materials depends not only on the chemical properties of the materials, but also on factors such as the concentration of ozone, contact time, and environmental conditions. In the case of high concentration or long contact time, the corrosive effect of ozone on the material will be more obvious. In addition, environmental factors such as temperature and humidity may also affect the corrosion process.
In summary, the ozone gas released by the ozone generator during operation does have a certain degree of corrosiveness to metal and non-metallic materials. Therefore, when selecting and using the ozone generator, it is necessary to fully consider the corrosion resistance of the material and take corresponding protective measures to reduce the impact of corrosion. At the same time, regular inspection and maintenance of equipment, as well as timely detection and treatment of corrosion problems, are also the key to ensuring the long-term and stable operation of the ozone generator.
