    Abstract: PURPOSE: Provided is a production process of an alumina pulverulent body by W/O type emulsion method which uses paraffin oil as dispersion solvent to control cohesion of the alumina pulverulent body, with changing reaction conditions to control granularity of the alumina pulverulent body. CONSTITUTION: The production process of the alumina pulverulent body by the W/O type emulsion method comprises the steps of: (i) mixing hydrophilic alumina sol as dispersion solute and oil as dispersion solvent, adding emulsifier and then stirring to produce W/O type emulsion; (ii) adding gelation agent to the produced W/O emulsion and make gel from the produced W/O emulsion; and (iii) firing the gelled emulsion.
