What Is Cadmium Sulfide?

There are two kinds of crystals of cadmium sulfide, -form is lemon yellow powder, -form is orange red powder. Slightly soluble in water, soluble in acid, slightly soluble in ammonia. Can be used for making fireworks, glass glazes, enamels, luminescent materials, pigments. High-purity cadmium sulfide is a good semiconductor and has a strong photoelectric effect on visible light. It can be used for making photovoltaic tubes and solar cells. It is prepared by passing hydrogen sulfide into an acid solution of a cadmium salt.

Risk Overview

Health hazard:

Acute poisoning: Causes respiratory tract irritation after inhalation, chemical pneumonia and pulmonary edema can occur; it can cause acute gastrointestinal irritation after misadministration, including nausea, vomiting, diarrhea, abdominal pain, post-emergency, general weakness, muscle pain and collapse .

Chronic poisoning: Chronic poisoning is mainly manifested by emphysema and impaired renal function (proteinuria); followed by iron deficiency anemia, hyposmia or loss.

Environmental hazards: It is harmful to the environment, and can cause pollution to water bodies and dust pollution.

Explosion hazard: The product is non-combustible and irritating. ^[1]

Industrial preparation of cadmium ore after leaching with sulfuric acid

Cadmium sulfide reacts with acid to form

Cadmium sulfide is mainly used as a pigment. Cadmium sulfide and cadmium selenide are used in the manufacture of photoresistors, solar cells, photocatalysts, etc.

pigment

Cadmium sulfide is called Pigment yellow 37. By adding different amounts of selenium, various colors can be obtained, such as CI pigment orange 20 and CI pigment red 108.
