Arsenic sulfide may refer to:
- Arsenic trisulfideArsenic trisulfideArsenic trisulfide is the inorganic compound with the formula As2S3. This bright yellow solid is a well known mineral orpiment , has been used as a pigment, and has played a role in the analysis of arsenic compounds. This chalcogenide material is a group V/VI, intrinsic p-type semiconductor and...
, As2S3, the mineral orpiment - Tetraarsenic tetrasulfide, As4S4, the mineral realgarRealgarRealgar, α-As4S4, is an arsenic sulfide mineral, also known as "ruby sulphur" or "ruby of arsenic". It is a soft, sectile mineral occurring in monoclinic crystals, or in granular, compact, or powdery form, often in association with the related mineral, orpiment . It is orange-red in colour, melts...
- Tetraarsenic trisulfide, As4S3, occurs as the minerals α- and β- dimorphiteDimorphiteDimorphite is a very rare orange-yellow chalcogenide mineral. In nature, dimorphite forms primarily by deposit in volcanic fumaroles at temperatures of 70°-80°C . Dimorphite was first discovered in a such a fumarole near Naples, Italy in 1849 by the mineralologist Arcangelo Scacchi...
