Liquid metal will wet to most metallic surfaces. Specifically though, room-temperature liquid metal can be very reactive with certain metals. Liquid metal can dissolve most metals; however, at moderate temperatures, only some are slightly soluble, such as sodium, potassium, gold, magnesium, lead, nickel and mercury. Gallium is corrosive to all metals except tungsten and tantalum, which have a high resistance to corrosion, more so than niobium, titanium and molybdenum. Similar to indium, gallium and gallium-containing alloys have the ability to wet to many non-metallic surfaces such as glass and quartz. Gently rubbing the alloy into the surface may help induce wetting. However,
Liquid metal devices, medical devices, interconnected devices and so on. Typical uses of liquid metals include thermostats, switches, barometers, heat transfer systems, and thermal cooling and heating designs. Uniquely, they can be used to conduct heat and/or electricity between non-metallic and metallic surfaces. Liquid metal is used extensively by overclockers and computer enthusiasts to replace the original thermal interface on CPU and/or GPU dies to improve cooling efficiency and performance. Also, liquid metal can be used for wearable devices. The Internet of Things (IoT) can improve our lives. Emerging IoT applications require reliable and effective wireless connectivity. Therefore, it is necessary to
