Scandium phosphide is an inorganic compound of scandium and phosphorus with the chemical formula Sc P.^[3]^[4]^[5]

Synthesis

ScP can be obtained by the reaction of scandium and phosphorus at 1000 °C.^[2]

4 Sc + P₄ → 4 ScP

This compound is calculated to be a semiconductor used in high power, high frequency applications and in laser diodes.^[6]^[7]

ScP can be smelted with cobalt or nickel through electric arc to obtain ScCoP and ScNiP.^[8]
