Item details

Antimony trioxide, Sb2O3, 99.5 %, 100, 250, 500, 1000, Grams

Antimony(III) oxide is the inorganic compound with the formula Sb2O3. It is the most important commercial compound of antimony. It is found in nature as the minerals valentinite and senarmontite.[2] Like most polymeric oxides, Sb2O3 dissolves in aqueous solutions with hydrolysis.

Global production of antimony(III) oxide in 2012 was 130,000 tonnes, an increase from 112,600 tonnes in 2002. China produces the largest share followed by US/Mexico, Europe, Japan and South Africa and other countries (2%).[3]

As of 2010, antimony(III) oxide was produced at four sites in EU27. It is produced via two routes, re-volatilizing of crude antimony(III) oxide and by oxidation of antimony metal. Oxidation of antimony metal dominates in Europe. Several processes for the production of crude antimony(III) oxide or metallic antimony from virgin material. The choice of process depends on the composition of the ore and other factors. Typical steps include mining, crushing and grinding of ore, sometimes followed by froth flotation and separation of the metal using pyrometallurgical processes (smelting or roasting) or in a few cases (e.g. when the ore is rich in precious metals) by hydrometallurgical processes. These steps do not take place in the EU but closer to the mining location.

Properties

Antimony(III) oxide is an amphoteric oxide, it dissolves in aqueous sodium hydroxide solution to give the meta-antimonite NaSbO2, which can be isolated as the trihydrate. Antimony(III) oxide also dissolves in concentrated mineral acids to give the corresponding salts, which hydrolyzes upon dilution with water.[4] With nitric acid, the trioxide is oxidized to antimony(V) oxide.[5]

When heated with carbon, the oxide is reduced to antimony metal. With other reducing agents such as sodium borohydride or lithium aluminium hydride, the unstable and very toxic gas stibine is produced.[6] When heated with potassium bitartrate, a complex salt potassium antimony tartrate, KSb(OH)2•C4H2O6 is formed.[5]

Uses

The annual consumption of antimony(III) oxide in the United States and Europe is approximately 10,000 and 25,000 tonnes, respectively. The main application is as flame retardant synergist in combination with halogenated materials. The combination of the halides and the antimony being key to the flame-retardant action for polymers, helping to form less flammable chars. Such flame retardants are found in electrical apparatus, textiles, leather, and coatings.[10]

Other applications:

Antimony(III) oxide is an opacifying agent for glasses, ceramics and enamels.
Some specialty pigments contain antimony.
Antimony(III) oxide is a useful catalyst in the production of polyethylene terephthalate (PET plastic) and the vulcanization of rubber.

Returns & exchanges

I can not offer returns, refunds or exchanges on chemical materials due to the fact that there is no guarantee that the material has not been tampered with and I can not resell it to someone else with confidence that I have the same materials that was originally purchased from my supplier. Therefore I repeat there are NO returns on chemical materials.

I offer exchanges only on Ceramic art for equal or greater value item. The buyer is required to pay to return the original item shipping and the new item shipping as well as 25% restocking fee. Also for clarity the Free shipping is no longer applicable on exchanged items. The new item will be shipped when the original item is received intact and the additional fees have been paid.
No item will be exchanged of a lesser value item with the buyer expecting refund.

Paintings are not returnable
