Gallium is a chemical element with atomic number 31. Solid gallium is a blue-grey metal having an orthorhombic crystalline structure, whereas very pure gallium is coated with stunning silvery colour. It does not exist in pure form in nature, and its compounds do not act as a primary source ...

Does gallium have high or low melting point? Gallium, with atomic number 31 and atomic weight of 69.723. Gallium is a soft, light silver metal. It largely exists as a trace element in minerals and compounds. Gallium is unique inits low melting point(average human body temperature is enough...
Is gallium in liquid state? Gallium remains in the liquid phaseover a temperature range of about 2,000 °C (about 3,600 °F), with a very low vapour pressure up to about 1,500 °C (about 2,700 °F), the longest useful liquid range of any element. The liquid metal clings to (we...
Mendeleev predicted the properties of some undiscovered elements and gave them names such as “eka-aluminum” for an element with properties similar to aluminum. Later “eka-aluminum” was discovered as gallium.(1869年,俄罗斯化学家德米特里·门捷列夫(Dmitri Mendeleev)创建了现代元素周期表的框架,为尚未...
Semiconductor materials include – Silicon,antimony, arsenic, boron, carbon, germanium, gallium arsenide, selenium, silicon carbide, sulfur, tellurium, oxides of most metals. What is Superconductor? Superconductor is an element, inter-metallic alloy, or a compound that conducts electricity without resist...
> materials which have a conductivity between conductors (generally metals) and nonconductors or insulators (such as most ceramics). Semiconductors can be pure elements, such as silicon or germanium, or compounds such as gallium arsenide or cadmium selenide. Translate 0 Kudos Copy lin...
While single-crystal silicon has been proven in extraterrestrial use with efficiencies as high as 18 percent, and other more expensive and scarce materials such as gallium arsenide can have even higher efficiencies, costs must be reduced by a factor of more than 100 to make them practical ...
Silicon: a chemical element and the main material used to create silicon chips and semiconductor devices; used in solar panels. Light-Emitting Diodes (LEDs): a semiconductor that emits light when an electrical current flows through it; often used in LED lights for lamps, digital watches, traff...
