| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| production method | gallium metal or gallium trioxide was dissolved in nitric acid. The solution was evaporated, concentrated and water was added. This was repeated until no nitric acid odor was present in the concentrated solution. It was then diluted with water to give 26g of gallium per 100ml of solution. Ga(NO3)3 · xH2O can be precipitated by cooling the viscous solution. The crystals were filtered off with suction and dried under vacuum at room temperature and then dried at 40 °c for 48h to give an anhydrous. |
