Therefore, seeding may be necessary to initiate solidification. Ultra-pure gallium has a beautiful, silvery appearance, and the solid metal exhibits a conchoidal fracture similar to glass. High-purity gallium is attacked only slowly by mineral acids. Uses Gallium wets glass or porcelain and forms a brilliant mirror when it is painted on glass. It is widely used in doping semiconductors and producing solid-state devices such as transistors.
Gallium arsenide is capable of converting electricity directly into coherent light.
Gallium readily alloys with most metals, and has been used as a component in low-melting alloys. Handling Its toxicity appears to be of a low order, but should be handled with care until more data is available.
