Abstract
PURPOSE:To obtain the titled sintered compact having excellent dimensional accuracy with hardly any warping, by colloidally dispersing a ceramic raw material powder and polycarboxylate in a solvent, adding and mixing a plasticizer and organic binder to provide a slurry, form, forming the resultant slurry into a green sheet and firing the obtained sheet. CONSTITUTION:A ceramic raw material (e.g. 90pts.wt. alumina powder), a sintering assistant (e.g. 10pts.wt. SiO2, MgO or CaO), and a polycarboxylate (e.g. NH4 salt in a volume of 0.8ml/100g inorganic powder) are colloidally dispersed in a solvent (e.g. ethanol) using a ball mill and a plasticizer (e.g. DBP) and an organic binder (e.g. polyvinyl butyral) are added and mixed to provide a slurry, which is then formed by a doctor blade forming method to afford a green sheet. The resultant green sheet is subsequently punched to a given dimension and fired in an electric furnace to provide the titled sintered compact.
