Copper has been considered as a common pressure calibrant and equation of state (EOS) and shock wave (SW) standard, because of the abundance of its highly accurate EOS and SW data, and the assumption that Cu is a simple one-phase material that does not exhibit high pressure (P) or high temperature (T) polymorphism. However, …

A pure substance is a substance that consists of only one type of particle. The particle can be an atom, a molecule, or an ion. In a pure substance, all the particles are identical. This means that they have the same mass, size, and chemical properties. One way to represent a pure substance is through a particle diagram.
