Elemental Form| Metallic antimony, a bluish-white metal, is extremely brittle, flaky and crystalline. Though sometimes found in its pure state, antimony is more frequently found as the sulfide, stibnite (Sb2S3), or as antimonides of heavy metals and as oxides. It is a poor conductor of heat and electricity and has a hardness of 3-3.5 on th Mohs scale. Antimony is used in the manufacture of alloys and as a hardening agent for lead. In its purest form, antimony is used in semiconductor technology. | ||||
