It''s Elemental - The Element Calcium

Today, metallic calcium is obtained by displacing calcium atoms in lime with atoms of aluminum in hot, low-pressure containers. About 4.2% of the earth''s crust is composed of calcium. Due to its high reactivity with common materials, there is very little demand for metallic calcium.

Separation of ethane and ethylene by a robust ethane

We report here the selective adsorption of ethane over ethylene by a robust microporous metal–organic framework (MOF) material, Ca(H2tcpb) (H4tcpb = 1,2,4,5-tetrakis(4-carboxyphenyl)-benzene). This compound exhibits higher adsorption capacity and stronger affinity …

Electrical Conductance Conductivity of Metal Semiconductor

Aug 25, 2018· When external electric source is connected to a piece of metal, these free electrons start flowing towards higher potential terminal of the source, causing current to flow in the metal. In metal, density of free electrons in conduction band is much higher than other materials, hence metal is referred as very good electrical conductor.
