Lithium phosphate manufacturing method

Abstract

A method of manufacturing lithium phosphate comprising: introducing a lithium-containing solution into a reactor; introducing an alkali material and a phosphorus supply material into the reactor; stirring the lithium-containing solution into which the alkali material and phosphorus supply material are introduced to grow lithium phosphate core particles and obtain a lithium phosphate suspension; and separating the suspension into solid and liquid to obtain the lithium phosphate, wherein one of the alkali material and phosphorus supply material is introduced into an upper portion of the reactor, and the other is introduced into a lower portion of the reactor.
