Antimonium crudum
1-253.65.15English: Antimonite; Antimony crudum; Antimony sulphide; Black sulphide of anitmony; Black sulphide of antimony; Stibnite,antimonite; Stibnitum.
Together with Cinnabaris this is one of the very few sulphides we know in the Materia Medica. Its chemical formula is Sb2S3, while Antimonium sulphuricum is Sb2(SO4)3. Antimonium sulphurosum is the sulphide. Sulphides are also called Sulphuratums.SignatureThe mineral form of Antimonium crudum is quite common and is called stibnite. It is mainly found in Japan on the island of Chikoku and in the mines at Ichinokawa. The crystals in this mine can reach a height of 60 cm with a width of 5 cm, which makes them useful as poles to fence of certain areas. The crystals usually lie at right angles to the magnetic field of the earth.
Antimonium also readily forms sulphides with the other metals. With lead it forms plagionite, boulangerite, semseyite, and zincenite. With lead and tin together it forms cylindrite and frankeneite, with mercury it forms livingstonite, with silver: miargite, pyrostilbnite, stefanite and pyrargyrite, with copper: chalcosine, tetraedrite and chalcostibite, with lead and silver: diaforite, with lead and copper: bournonite, with iron: gudmundite, and with nickel: ullmannite.
