Abstract

Bereitstellung eines Lithium-Silicophosphat-Pulvers, bei dem die Korngröße der Primärpartikel einheitlich ist und das auch bei einer niedrigen Temperatur gesintert werden kann und somit hervorragende Sintereigenschaften hat. Lithium-Silicophosphat-Pulver, wobei es sich beim Lithium-Silicophosphat um ein durch die folgende allgemeine Formel (1): LixSii-yPyO4 (1) (wobei x für 3,00 < x < 4,00 steht, y für 0,00 < y < 1,00) ausgedrücktes Lithium-Silicophosphat handelt, dadurch gekennzeichnet, dass bei einer Beobachtung mittels eines Rasterelektronenmikroskops (REM) die mittlere Korngröße der Primärpartikel 0,1 bis 1,5 |um beträgt, und die Standardabweichung o der Korngröße kleiner oder gleich 1,5 |um ist.
