- Gallium is a chemical element with atomic number 31. The Solid gallium is of blue-gray metal having orthorhombic crystalline structure whereas a very pure gallium is coated with stunning silvery color.
- It does not exist in pure form in nature, and its compounds do not act as a primary source of extraction
- It is used in Blue-ray technology, blue and green LEDs, mobile phones and pressure sensors for touch switches.
- Gallium nitride acts as a semiconductor. It consists of certain properties that make it very versatile.
- This metal can be easily extracted as a by-product from iron pyrites, zinc blende, germanite, and bauxite.
- It is solid at room temperature but when it comes in contact with cesium, mercury, and rubidium it becomes liquid (when heated slightly).
- This element has been considered as a possible heat exchange medium in nuclear reactors.
- When Gallium is added to certain metals it causes them to become brittle.
- Gallium has one of the largest ranges in which it is a liquid when compared to other metals.
