Antimony | Geoscience Australia

In the modern era, antimony is rarely used in pure form owing to the metal's tendency to be brittle and flaky. It is most commonly used with other metals to form alloys or combined with oxygen to form antimony trioxide (ATO; Sb 2 O 3). Metallic antimony is used as a hardening agent for lead and its use in lead storage batteries accounts for ...

Antimony | Sb - PubChem

Antimony is alloyed with other metals such as lead to increase its hardness and strength; its primary use is in antimonial lead, which is used in grid metal for lead acid storage batteries. Antimony oxides (primarily antimony trioxide) are used as fire retardants for plastics, textiles, rubber, adhesives, pigments, and paper.
