Abstract

Lithium nitride with compact polycrystalline structure. The desired prod. is made by crushing lithium nitride and then placing the powder thus obtd. in a die contg. a press punch so the powder can be sintered at 400-815 degrees C, unser a max. pressure of 2000 kg/cm2; the punch and die are made of a material which is chemically inert w.r.t. lithium nitride. Sintering pref. occurs in an inert atmos., or in N2; and the compact polycrystalline lithium nitride (CPLN) is pref. employed as an ionic conductor for Li ions or as electronic insulation. The CPLN is used esp. in a battery contg. a so solid electrolyte; in an electrochromic visual display indicator; or in appts. measuring the concn. of Li ions or nitrogen. The CPLN possesses electrical and mechanical properties similar to those of a monocrystal; but monocrystals are costly to make and the invention avoids such expense.
