Indium sulfide (In2S3) - Reference Information
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| solubility in water (g/100ml) | dissolved grams per 100ml of water: 2.867 × 10-14/20 ℃ |
| production method | put a small corundum disc containing indium trioxide into a quartz tube, and under the condition of introducing hydrogen sulfide purified by dry ice liquefaction, heat the reaction tube to 500 ℃ for 5 hours, then raise the temperature to 700 ℃ for 8 hours. The product is the red indium trisulfide, which becomes a shiny black product after melting. This product is a high-temperature modified product of β-In2S3. The low-temperature variant product α-In2S3 can be prepared by the following method: that is, to the trivalent indium salt solution dissolved in the acetic acid salt buffer aqueous solution, hydrogen sulfide is introduced, and the generated precipitate is deposited at a temperature below 100°C., Vacuum drying on P2O5 is obtained. But it is difficult to make pure products. |
