- Antimony (Sb) Metal Synonyms:
antimony metal, antimony powder, Sb, stibium, black antimony- black, CAS# 7440-36-0,
- Antimony (Sb) Metal Designations:
Chemical Name: Antimony
Chemical Formula: Sb
a) Metallic antimony, a bluish-white metal, is extremely brittle, flaky and crystalline. Although sometimes found in its pure state, antimony is more frequently found as the sulfide, stibnite (Sb2S3), or as antinomies of heavy metals and as oxides. It is a poor conductor of heat and electricity and has a hardness of 3-3.5 on the Mohs scale.
b) Antimony is used in the manufacture of alloys and as a hardening agent for lead. In its purest forms, antimony is used in semiconductor technology.
Purities available from 99.5% to as high of a typical purity as 99.999%
Numerous particle size options are available from as large as aluminum notched bar ingots down to as small as 20-100 nanometers.
