A new type of high temperature superconductor is described which is based on cubic phase Li3P formed at high pressures. A method for creating Li3P in a cubic phase either by itself or with up to 10% of Li3N by molecular proportions is also presented. The synthesis of these superconductive compounds is described. Generally, a mixture of low pressure synthesized Li3N and Li3P is subjected to a combination of high pressure and high heat for a certain duration. The phases are monitored during synthesis with x-ray diffraction and mass-spectrometry. The resultant materials display superconducting transitions, TS, above 225 K and approaching room temperature.
