实验性质
| 外观 / 形态 : | Anhydrous aluminum sulfate is a white crystalline solid. Aluminum sulfate is also obtained as an 18-hydrate Al2(SO4)3.18H2O. Both forms are soluble in water, noncombustible, and nontoxic. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. It is used in paper making, in firefighting foams, and in sewage treatment and water purification.；Aluminum sulfate, solution appears as a clear colorless aqueous solution. Noncombustible. Nontoxic. Density 10.9 lb / gal. Used in paper making, in firefighting foams, as a fireproofing agent, in sewage treatment and water purification.；Dry Powder; Other Solid; Large Crystals; Liquid; Liquid; Dry Powder; Liquid；White powder, shining plates or crystalline fragments；White solid; [Merck Index] Hygroscopic; [CHEMINFO] White powder; [MSDSonline]；ODOURLESS WHITE HYGROSCOPIC LUSTROUS CRYSTALS OR POWDER. |
