Cadmium pigments are a class of cadmium-containing pigments. Most of the cadmium produced worldwide was used in nickel-cadmium rechargeable batteries, which were replaced by other types of rechargeable nickel-chemical cells, such as NiMH cells, but about half of the consumption remained cadmium, which consumed about 2,000 tonnes (2,200 short tons). ) per year is used to produce colored cadmium pigments. The main pigments are a family of yellow, orange and red cadmium sulfides and sulfoselenides and compounds with other metals. Cadmium is toxic to humans and other animals in very small amounts, especially when inhaled, which is often the case when working with powdered pigments or inhaling chalk dust. Therefore, it is inappropriate for children to use art materials that contain cadmium pigments. However, because pigments have certain desirable properties, such as B. Fade resistance, they are still used by some adult artists.
