CHEMICAL AND PHYSICAL PROPERTIES
Physical Description | Gallium is a silvery-white liquid at room temperature. Ingestion of this material may be toxic. It is corrosive to aluminum. If exposed to high temperatures, gallium may emit toxic fumes which may form a corrosive alkaline solution with water. It is soluble in most acids and alkalis. It is used as a semiconductor material. |
