MANUFACTURING METHOD OF LITHIUM SILICATE POWDER

摘要

A manufacturing method of lithium silicate powder is provided to produce the lithium silicate powder of high quality, and to improve absorption property of carbon dioxide dramatically by widening a contact area of the carbon dioxide. A manufacturing method of lithium silicate powder includes the following steps of: producing sol for spraying using silicon alkoxide which is a supply source of lithium acetate and silicate; forming precursor powder through an electrostatic spraying process of the sol; and forming crystalline powder by heat-treating the precursor powder. A molar ration of the lithium and silicon is 1 ~ 4 : 1. A thermal process is performed to the temperature of 600 ~ 900‹C.
