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.
PHYSICAL&CHEMICAL 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 90℃, the metal variant is the stable form of antimony with the melting point of 630℃, density of 6.62g/cm3 and bad thermal conductivity.
