Antimony Compounds

Antimony is a silvery-white metal that is found in the earth's crust. Antimony ores are mined and then either changed to antimony metal or combined with oxygen to form antimony oxide. (1) Antimony xide is a white powder that is very slightly soluble in water. (1) Antimony metal is a very brittle, moderately hard metal. (1)

Antimony Ingot | AMERICAN ELEMENTS

American Elements produces metallic Antimony Ingots with the highest possible density. Ingots are generally the least costly metallic form and useful in general applications. Our standard Ingot size is nominally 2-3 cm x 3-8 cm x 6-12 cm. Materials are produced using crystallization, solid state and other ultra high purification processes such ...

Peculiar Structural Phase of a Single-Atom-Thick Layer of Antimony

Using molecular beam epitaxy, a new structural phase of a single atom thick antimony layer has been synthesized on the W(110) surface. Scanning tunneling microscopy measurements reveal an atomically resolved structure with a perfectly flat surface and unusually large unit cell. The structure forms a well-ordered continuous film …
