This substance is thought to be a type of nitrate formed by nitrogen and moisture in the air. This salt adsorbs moisture in the air and deliquesces, thereby producing conductivity, thereby making the electrical characteristics of the ozone generating plate Φ tube unstable. This causes the following trouble.
