Abstract

The present invention provides a process for the production of solid in conductor materials based on the following formula: EQU A.sub.3u+2v+w XuYuZw wherein A is lithium or sodium, X is nitrogen, phosphorus or arsenic, Y is nitrogen, sulphur, tellurium or selenium, Z is hydrogen or a halogen, and u, v, and w each represent a number from 0 to 1 inclusive, with the proviso that only one of u, v, and w can assume the value of 0.
