As calcium is classified as a solid and metal, it does conduct electricity and heat. Like most metals, calcium is a relatively good conductor of heat and electricity.
Is Calcium Conductive
The silvery-white solid calcium is a pretty fair conductor of electricity. The metallic bonding in calcium allows the delocalized electrons to flow freely from atom to atom, conducting electricity. However, copper or aluminum is a better conductor by volume, but calcium is better by mass than both due to its very low density.
Do Calcium Conducts Electricity
As we know, metals are good conductors of electricity as well as heat because they contain mobile electrons. Calcium is classified as a solid and metal, so calcium conducts electricity.
What Is the Conductivity of Calcium
The electrical Conductivity of the Calcium is 2.9×10^7 S/m. Measurements have shown the electrical conductivity of single crystals of calcium oxide, the conductivity was 1 × 10-8 ω-1 cm-1 at 1050°K.
Is Calcium a Bad Conductor
Even though calcium conducts electricity quite well, it is unstable and unsuitable for any structural purpose in its pure metallic form. Also once isolated, it is very reactive and forms a grayish-white oxide and nitride coating when exposed to air. So, calcium is not used in wires or any electric circuitry.
Does Calcium Increase Conductivity
Tests have shown results that an increased concentration of calcium increases conductivity significantly. Calcium can be found mostly in salt form in nature and as dissolved salts and other inorganic chemicals conduct electrical current, conductivity increases for increased salinity.
The research was conducted at the sample sites on the north shore (Valois Bay – filled triangles and Lachine – open triangles) and the south shore (Chateauguay East – open circles and Chateauguay West – closed circles) of Lake St. Louis. Valois Bay (dashed line) and Lachine (dotted line) show a relationship between calcium concentration and conductivity at the sample sites.
For Valois Bay (dashed line in the graph) and Lachine (dotted line in the graph), the relationship was positive, while it was negative in Chateauguay West (solid line in the graph).
Even though calcium is conductive enough to conduct electricity, it is not used for practical purposes for its high reactive characteristics and nitride coating when exposed to air.
