Abstract: It was mainly studied that the effect of the inorganic -organic composite plasticizer on the characteristic of extrusion molding and sintering of poor plastic ceramic materials .The results show that with the proper compounding of the plasticizer, the extrusion molding of the poor plastic ceramic materials can be completed well and the severe sintering shrinkage resulted from the improper introduction of the plasticizer can be solved too .Therefore, it can make the production' s sintering shrinkage lower than 1 ～ 2 % and can ensure the dimensional stability of the production is good enough .

Keywords: poor materials, extrusion molding, plasticizer
