13464-82-9 - Reference Information
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| use | preparation of indium plating solution |
| production method | crystal of In2(SO4)3 · H2SO4 · 7H2O can be precipitated by dissolving indium or In2O3 in large excess dilute sulfuric acid under heating and concentrating at 50 ℃. The crystals are pumped out with a glass sand core funnel, washed with glacial acetic acid and dried. Heat the prepared acid salt until no more sulfuric acid volatilizes (450°C, about 6 hours) to generate anhydrous indium sulfate. It is also possible to prepare an indium sulfate solution first, concentrate the solution and crystallize an orthorhombic crystal of In2(SO4)3 · 5H2O from it. This crystal is heated at a temperature of about 500°C for 6 hours to decompose to generate anhydrous indium sulfate. |

| storage and transportation characteristics | warehouse ventilation and low temperature drying |
| fire extinguishing agent | dry powder, foam, sand, carbon dioxide, mist water |
| occupational standard | TWA 0.1 mg (indium)/m3 |
