What are alloy compounds in the production of electric light sources?
Generally speaking, an alloy compound is a new substance formed by chemically combining two or more metal (or metal and nonmetal) elements in a fixed ratio. It's not a simple mixture, but rather a compound formed by rearranging the atoms at the atomic level to form a distinct lattice structure.
Their characteristics are:
1. A defined chemical formula, such as CuZn, FeAl, and Ni₃Al.
2. An independent lattice structure, for example, completely different from that of the original metal.
3. Significantly different properties: Their physical and chemical properties are often distinct from those of the original metal.
4. Stable chemical bonds: The chemical bonds between the elements remain unchanged during the transition from liquid to solid.
5. Significantly different elements: They are often formed from elements that are far apart on the periodic table and have significantly different properties.
Let me give you an example:
Aluminum and nickel can form Ni₃Al (nickel-aluminum compound), which is much stronger and more heat-resistant than either nickel or aluminum alone.
Alloy compounds are very important in the production of electric light sources. They can generate properties that a single element does not have, thus being better used in production.
