Abstract
A production method for zeolite powder containing forming zeolite seed crystals by wet pulverizing zeolite crystals using a silica unsaturated alkali solution containing an alkali source, preparing a silica saturated alkali solution by adding a silica source to the silica unsaturated alkali solution containing the zeolite seed crystals, and synthesizing zeolite powder by hermetically heating the silica saturated alkali solution.
