Strontium compounds, electrical

Davy also discovered several other elements (potassium, barium, calcium, and strontium) by isolating the metals from their compounds through electrolysis. His work led to the development of electrochemistry, which is the use of electricity as the energy source to break up the oxides of these alkali and alkali earth elements. 

Strontia was later found to be a compound of strontium and oxygen. In 1808, Davy found a way to produce pure strontium metal. He passed an electric current through molten (melted) strontium chloride. The electric current broke the compound into its two elements ... 

The electrical resistivity and thermopower of metallic calcium, strontium, and barium have been measured from room temperature to near their melting points. From discontinuities observed in these parameters as functions of temperature, the f.c.c.-b.c.c. phase transition was determined in calcium at 428 2 °C and in strontium at 542 2 C, both at ambient pressure. Four compounds have been identified in the Ca-Ni system by means of X-ray methods. The intermetallic...
