The melting point of Sb 2 S 3 is 823 K (550 °C; 1,022 °F). [9] The band gap is 1.88 eV at room temperature and it is a photoconductor. [ 10 ] Stibnite is also toxic upon ingestion, with symptoms similar to those of arsenic poisoning .
2 Sb + 3 S → Sb 2 S 3. Sb 2 S 3 is precipitated when H 2 S is passed through an acidified solution of Sb(III). [9] This reaction has been used as a gravimetric method for determining antimony, bubbling H 2 S through a solution of Sb(III) compound in hot HCl deposits an orange form of Sb 2 S 3 which turns black under the reaction conditions.

Antimony triselenide is the chemical compound with the formula Sb 2 Se 3. The material exists as the sulfosalt mineral antimonselite (IMA symbol: Atm [2]), which crystallizes in an orthorhombic space group. [3] In this compound, antimony has a formal oxidation state +3 and selenium −2.
The total mineralised area of the mine has a surface extent of 14 km 2. There are two different units at the mine, the northern one produces mixed oxide and sulfide such as stibiconite (Sb 3 O 6 (OH)) and the southern one produces stibnite. Ore is concentrated and refined on site in a refinery with a capacity of 10,000 tonnes of antimony per ...

The antimonide ion is Sb 3− but the term refers also to any anionic derivative of antimony. [1] Antimonides are often prepared by heating the elements. [2] ntimony by alkali metals or by other methods leads to alkali metal antimonides of various types. [3] Known antimonides include isolated Sb 3− ions (in Li 3 Sb and Na 3 Sb).
These are formally salts of antimonous acid, [2] Sb(OH) 3, whose existence in solution is dubious. Attempts to isolate it generally form Sb 2 O 3 ·xH 2 O, antimony(III) oxide hydrate, which slowly transforms into Sb 2 O 3. [1] In geology, the mineral stibnite, Sb 2 S 3, is sometimes called antimonite.
