Preparation of sulphides |
| abstract |
Sulphides are prepared by combining a dithionite compound with an aqueous alkaline solution of an appropriate cation or mixture of cations. On heating the corresponding sulphides are precipitated. The dithionite compound may be a dithionite dianion which is produced as an intermediary when thiourea dioxide is used as a starting material in the solution. Examples of appropriate cations are zinc (as zinc acetate) and copper (as copper acetate). The precipitate is dried and subsequently fired to produce high quality sulphides which may be used as phosphors or other optoelectronic materials. |
