Antimony ore of high quality in Laos by Lao Mining
Antimony is a silvery, lustrous gray metal that has a Mohs scale hardness of 3. Thus pure antimony is too soft to make hard objects. Four allotropes of antimony are known: a stable metallic form and three metastable forms (explosive, black and yellow). Metallic antimony is a brittle, silverwhite shiny metal....
