Bulk Lump Antimony Ore

Product Overview

Description

 

Chemical Formula	Sb
Composition	Antimony, often with small amounts of arsenic, iron, silver, and sulfur
Variable Formula	(Sb,As) ; (Sb,As,Fe,Ag,S)
Color	Tin-white, with a very light blue tinge. Oxidizes gray to dark gray, and the blue tinge is indiscerniblewhen oxidized.
Streak	Black
