Abstract
To produce ceramic lithium nitride as solid electrolyte for galvanic lithium cells, Li.sub.3 N powder is first stirred together with molten Li-metal serving as binder, in a noble gas atmosphere. After cooling, the mixture is pressed into a shaped body and the shaped body is then sintered in nitrogen at temperatures of about 700.degree. C. This causes the Li-binder to also become transformed into Li.sub.3 N. The binding with lithium also makes the powdery starting material suitable for rolling, and shaped bodies such as tablets can be cut out of the ductile rolled product with high precision.
