Overview of Arsenic Sulfide As2S2
Arsenic sulfide is an inorganic compound with the chemical formula As2S3, also known as arsenic sulfide. The ore, called orpiment, is a common mineral of realgar (arsenic disulfide) and is a common "miner". Pure arsenic trisulfide is lemon yellow, belongs to the monoclinic crystal system, and is composed of (As2S3)N layered lattice. It melts into a red liquid at 300℃, and does not decompose when it boils at 707℃. Arsenic trisulfide is insoluble in water and inorganic acids, but soluble in sodium sulfide, alkali metal hydroxides and carbonates. poisonous. Na3ASS3 is called sodium thioarsenite and can also exist in the form of impregnated NaASS2. Thioarsenous acid is unstable and easy to decompose
Arsenic trisulfide As2S2 is a semiconductor with a direct band gap of 2.7 eV. Its wide band gap makes it transparent to infrared rays from 620 nm to 11 μm.
As2S3 exists in two forms: crystalline and amorphous. Both forms have a polymer structure consisting of triangular pyramidal As(III) centers connected by sulfide centers. The sulfide center is doubly coordinated to two arsenic atoms. In crystalline form, the compound has a corrugated sheet structure. The bonds between the flakes consist of van der Waals forces. Crystalline forms are commonly found in geological samples. Amorphous As 2 S 3 has no layered structure, but has a high degree of cross-linking.
Realgar belongs to the monoclinic system, and the crystal group is P2(1)/n. The crystals are orange-red, transparent to translucent realgar crystals, and the columnar crystals vary in length and thickness, and grow in multiple directions. The crystal is diamond luster, and the fracture is resin luster. Single crystals are small columnar and needle-shaped, but natural single crystals are rare.
Application of Arsenic Sulfide As2S2
Arsenic minerals are mainly used to extract elemental arsenic to produce arsenic acid and arsenic compounds, such as calcium arsenate, sodium arsenate, lead arsenate, etc. In the metallurgical industry, it is used to make arsenic alloys; arsenic lead alloys are used in the military industry to make bullets, military drugs and fireworks; arsenic copper alloys are used to make radar parts and automobiles; light industry is used to make opal glass, glass decolorization, wool Soaking, tanning agent, wood preservation, etc.; used in agriculture as pesticides, herbicides, rodenticides and other arsenic-containing pesticides; arsenic products are called arsenic. Realgar concentrate powder can be used to make firecrackers and fireworks.
Arsenic trisulfide can be used as pigment, reducing agent and medicine.
Since the refractive index of As2S3 is 2.45 higher than that of organic photoresists, and the Knoop hardness is higher, the fabrication of photonic crystals with full photonic band gaps was investigated. Research advances in laser platemaking techniques, such as 3D direct laser engraving (3D DLW) and chemical wet etching, allow AS2S3 to be used as a photoresist to prepare 3D nanostructures.
AS2S3 and AS4S4 are used as treatments for acute promyelocytic leukemia (APL).
Amorphous arsenic trisulfide is used as chalcogenide glass in infrared optics. It is transparent between 620 nm and 11 μm.
Arsenic trisulfide glass is more resistant to oxidation than crystalline arsenic trisulfide, thus minimizing toxicity.
