Abstract: Sodium polyacrylate of different molecular weight was synthes ized under different reactive condition and it was used as reinforcing agent of the artis tic ceramic body .The effect of sodium polyacrylate on the s trength of the ceramic body and the degree of deformation was researched . The results show: through adding sodium polyacrylate into the ceramic body which may effectively increase the s trength of the dry body and decrease the degree of deformation of the dry body .When reinforcing agent c adding content is 0.6%, the s trength increas ing rate of the dry body is 167.5%,and the deformation rate of the dry body is decreased from 50% to 10% .
