2011-11-7 arsenic sulphide scaling can also occur under similar circumstances. The combination of lower brine temperatures and lower pH can lead to significant antimony sulphide scaling. Although the antimony concentration in the brine can be very low, antimony sulphide

2007-5-31 Mechanochemical reduction of antimony sulphide Sb 2 S 3 with elemental iron as reducing element (1) was performed in a planetary mill Pulverisette 6 (Fritsch, Germany). Tungsten carbide (WC) grinding chamber of 250 ml volume and 50 WC balls of 10 mm diameter (total weight 360 g) were used. Weight of powder for milling was 3 g.

2020-4-23 Antimony(III) sulphide is contained in the match heads together with potassium chlorate. When rubbing against the friction surface, which consists of red phosphorus, there is a small jet of flame which ignites the match. Antimony(III) sulfide is also found as an additive in fireworks.

2010-12-1 The antimony-bearing sulphide material used in this investigation was bought from Gregory, Bottley Llooyd Company, United Kingdom and originated from Casapalca, Departamento Lima, Peru. The coarse material was first crushed and part of its associated quartz was removed by handpicking prior to grinding.

2014-9-17 The inhibiting effect of the decomposition products of arsenic and antimony sulphide minerals on gold dissolution is not due primarily to oxygen depletion of the cyanide solutions, nor is it due to the precipitation of gold by these compounds; it is suggested that sulphide decomposition products are attached to the gold surface and interaction of CN ions, oxygen,

Six workers exposed to antimony trisulfide (used as a pigment and in match production) at concentrations greater than 3.0 mg m −3 in a factory that produces grinding wheels experienced heart complications and died, and the rest of the population working in the environment showed limited cardiovascular changes. Inhalation of antimony hydride (stibine gas) can lead to hemolytic anemia, renal failure, and hematuria.

2012-11-15 SnS has always been observed to be a p-type semiconductor. Doping SnS to form an n-type semiconductor would permit the construction of solar cells with p-n homojunctions. This paper reports doping SnS films with antimony, a potential n-type dopant. Small amounts of antimony (∼1%) were found to greatly increase the electrical resistance of the SnS.
