Abstract:Using inorganc aluminous salts as Preursors and hexamethylenetetramine as the catalyst.alumina nanonPowder was fabricated by sol一gel procedure and then incorPrated in the PreParation of body batch for thiekly一glazed,thin一bodied celadon waers.The study of the nanonPowder’s reinforcing effect on celadon ceramics showed:basically,the xe『rogel tranformed into α一Al₂O₃ at 980℃,and reacted with SIO₂ in clay to form mullite at 1250℃,thus increasing the thin Porcelain  body`s resistance to ther of the thick glaze in the cooling process.Inconsistent thermal expansion coefficients of body and glaze resulted in crackle on the glazing surface,which became a decoration for celadon wares.
