METHOD FOR PRODUCING β-EUCRYPTITE FINE PARTICLES

摘要

Provided is a production method characterized in that a mixed solution containing water-soluble lithium salt, water-soluble aluminum salt, and colloidal silica in a molar ratio with respect to lithium atoms, aluminum atoms, and silicon atoms (Li:Al:Si) of 1:1:1 is dried by spraying in an atmosphere having a temperature of from 50°C to less than 300°C, and then the solution is fired in an atmosphere having a temperature of 600-1,300°C.
