Antimony(III) oxide is the inorganic compound with the formula Sb 2 O 3. It is the most important commercial compound of antimony . It is found in nature as the minerals valentinite and senarmontite. [ 3 ]
Antimony is a chemical element; it has symbol Sb (from Latin stibium) and atomic number 51. A lustrous grey metal or metalloid, it is found in nature mainly as the sulfide mineral stibnite (Sb 2 S 3). Antimony compounds have been known since ancient times and were powdered for use as medicine and cosmetics, often known by the Arabic name kohl. [11]
The hydrated oxide is insoluble in nitric acid, but dissolves in a concentrated potassium hydroxide solution to give potassium hexahydroxoantimonate(V), or KSb(OH) 6. [6] When heated to 700 °C (1,290 °F), the yellow hydrated pentoxide converts to an anhydrous white solid with the formula Sb 6 O 13, containing both antimony(III) and antimony(V).

Perpetua Resources, which is building a U.S. antimony and gold project with support from the Pentagon, had planned to begin production by 2028, but is studying ways to produce antimony faster in ...
Valentinite is an antimony oxide mineral with formula Sb 2 O 3. Valentinite crystallizes in the orthorhombic system and typically forms as radiating clusters of euhedral crystals or as fibrous masses. It is colorless to white with occasional shades or tints of yellow and red. It has a Mohs hardness of 2.5 to 3 and a specific gravity of 5.76. [5]
China is a major producer of antimony, and some U.S. policymakers have worried about being overly dependent on China as a source. The mineral's uses include flame retardants, batteries, night ...
