What are some interesting facts about Antimony? | AnswersDrive Word origin: Antimony was named after the Greek words anti and monos to mean “a metal not found alone.” The chemical symbol, Sb, comes from the element's historical name, stibium. Discovery: Antimony was a known metal in the 17th century and was likely used even earlier.

Antimony - Arkansas Geological Survey Antimony is a hard, brittle, silver-white metal with a relatively high specific gravity (6.69) and a relatively low melting temperature. Antimony is a constituent in some alloys. The presence of this metal hardens the alloy, lowers the melting point, and decreases contraction during solidification.

How to melt antimony - A little tin in the lead makes the antimony stay disolved and behave like it is part of the plan. Without some tin the antimony oxidizes easily and in high percentages will even make a floaty slush. It has been my experience that about a 3 to 1 antimony to tin ratio works best for a smooth lovely alloy that stays evenly mixed..

USAC Metallurgy - us antimony METALLURGY. LIQUATION: Liquation is the melting of stibnite into “crudum” or “needle antimony”. It is carried out between 550 and 600 degrees C. If the temperature is lower, the recovery is poor. If the temperature is any higher, the stibnite volatilizes into oxide. This method is used to upgrade low-grade ores.
