High Purity Arsenic Sulfide As2S3 Powder CAS 1303-32-8, 99.99%

Arsenic Sulfide (As2S3) Powder:
Arsenic Trisulfide Is an inorganic compound. Arsenic sulfide Chemical Formula It is also called As2S3. arsenic sulfide Ore called "female yellow", realgar co-mineral (arsenic dioxide), a common mineral mandarin duck. Pure arsenic sulfide The liquid is red at 300 and boils at 707, without decomposition. Yellow arsenic Sulphide Insoluble in water, inorganic acids and carbonate. But soluble with sodium sulfide and alkali-metal hydroxides. To be poisonous.
It is also called sodium thioarsenite and is available as the macerate NaASS2. The thioarsenite acids is very unstable and decomposes easily.
Arsenic 3 sulfide This semiconductor has a direct bandgap value of 2.7 eV. Its wide-bandgap allows it to be infrared-transparent between 620nm & 11mm.
As2S3 can be found both in its crystalline and amorphous state. Both forms consist of polymeric structures made up of triangular As(III), cone-shaped centers, connected by centers of sulfide. The sulfide centers are double coordinated with two arsenic-atoms. In its crystalline form, this compound has a sheet structure with ruffles. The van der Waals force is responsible for the bonding between sheets. Crystalline forms can be found in most geological samples. Amorphous AS2S3 The cross-linking is more intense, even though the lamellarity of the structure is not present.

What is Arsenic Sulfide (As2S3) Powder produced?
By adding hydrogen sulfide or by eutectic combustion of sulfur and arsenic, arsenic can be converted to trisulfide. The following method can be used to prepare arsenic.

By fusing elements at 390degC, amorphous As2S3 can be obtained. Rapid cooling causes the reaction to turn into glass. A chemical equation can be used for the reaction:
2 as + 3 S-As2S3
Water precipitation
As2S3 can be formed when H2S is added to an aqueous As(III). This reaction was previously used to analyze and measure arsenic. As2S3 will precipitate even in 6M HCl. AS2S3 has a very low solubility, and is therefore not toxic.

Uses of Arsenic Sulfide :
The properties of arsenic triosulfide are useful for the separation and identification arsenic compound. Besides, it can be used for the following purposes:
The arsenic triosulfide compound can be used for a variety of purposes, including as a medicine, pigment and reducing agent.
As2S3's high refractive indices of 2.45, and its higher Knoop hardness compared to organic photoresists have been studied for fabricating photonics crystals with full photonic bandsgaps. AS2S3 is a photoresist that can be used for 3D nanostructures thanks to advances in laser plate making technologies such as 3D Direct Laser Engraving (3D DLE) and chemical wet Etching.
AS2S3 and AS4S4 are being studied as treatment for acute promyelocytic (APL).
It is used as a chalcogenide in infrared optical systems. Transparent between 620nm and 11mm.
The glass made of arsenic is less toxic because it's more resistant to oxidation.

Arsenic Sulfide (As2S3) Powder Storage Conditions:
