Atomic Structure and Properties

The atomic structure of zinc dictates its fundamental properties. With an electron configuration of [Ar] 3d10 4s2, zinc has a full d-subshell and a full outer s-subshell. This electron configuration contributes to its relatively stable nature and its metallic bonding characteristics. Zinc is a reasonably good conductor of electricity and heat, though not as efficient as copper or silver. It is also known for its relatively low melting point (419.5 °C or 787.1 °F) and boiling point (907 °C or 1665 °F) compared to many other metals. This low melting point makes it highly suitable for die casting processes, a key application in the automotive and electronics industries prevalent in regions like Hiroshima. Chemically, zinc is a reactive metal that readily oxidizes when exposed to moist air, forming a protective layer of zinc carbonate that prevents further corrosion – a property known as passivation, which is fundamental to its use in galvanizing. Its divalent cation (Zn2+) is also important in biological systems and various chemical compounds.

Common Impurities and Their Effects

While high-purity zinc (99.9% or greater) is standard for many industrial applications, common impurities can sometimes be present, even in small amounts. These typically include lead (Pb), cadmium (Cd), iron (Fe), and copper (Cu). The presence and concentration of these impurities can significantly alter zinc’s properties. For example: Lead (Pb) can reduce zinc’s corrosion resistance and make it more brittle. Cadmium (Cd), though sometimes present in trace amounts, can enhance corrosion resistance in certain environments but poses environmental and health risks. Iron (Fe) can form brittle phases, reducing ductility and potentially affecting corrosion performance. Copper (Cu), often present from smelting processes, can slightly increase tensile strength but may also impact corrosion resistance negatively in specific conditions. For applications requiring the highest performance, such as in advanced electronics or specialized alloys used in Hiroshima’s industries, controlling these impurities is paramount. Suppliers must ensure that the zinc metal contains only acceptable levels of these elements.
