Effect of Complex Additives on Ceramic Slip Mobility

Resumo

The effect of a number of additives on the rheological properties of clay was investigated. The change in the maximum dynamic shear stress and plastic viscosity as a function of the concentration of complex additives was examined. It is shown that technical-grade lignosulfonate can be used as one of the components of a complex thinning additive for clays. It is found that lignosulfonate used in combination with sodium tripolyphosphates improves the casting characteristics of the ceramic body.
