| Usages: |
| The largest applications for metallic antimony is an alloy with lead and tin and the lead antimony plates in lead-acid batteries. Alloys of lead and tin with antimony have improved properties for solders, bullets, and plain bearings. Antimony compounds are prominent additives for chlorine and bromine-containing fire retardants found in many commercial and domestic products. An emerging application is the use of antimony in microelectronics. |
| properties: |
| Antimony is a kind of non-ferrous heavy metals in shiny silver-white solid form of brittle property. It has two allotropes -the yellow variant is stable under the temperature of minus 90ºC, the metal variant is the stable form of antimony with the melting point of 630ºC, density of 6.62g/cm3 and bad thermal conductivity. |
Application
Antimony could be used in different fields, according to its purity. Primarily used in flame retardant applications due to its poor heat conductivity. Antimony metal is used as an alloy hardener as well as in metallurgical applications
