Antimony compounds are chemical substances that contain the element antimony, which is a metalloid. These compounds can be found in various forms, including oxides, sulfides, and halides. They are used in a range of applications, such as flame retardants, batteries, and in the production of certain alloys. Some common antimony compounds include antimony trioxide, which is often used as a flame retardant in plastics, and antimony sulfide, which is used in the production of pigments. While antimony itself is toxic in high doses, many of its compounds have specific industrial uses that are carefully regulated to ensure safety.
