The present investigation is a follow‐up of study on the extrusion of ceramic Raschig ring as a function of composition. The pastes were formulated using typical kaolin, polyvinyl alcohol, and carboxymethyl cellulose normally used in industrial scale. The effect of binders on the mechanical behavior of rings was studied from view point of mixture design algorithm to optimize the ceramic body composition. This method was shown to yield valuable information on the effect of binders on mechanical properties. The study was concluded that the reliability of ring can be effectively promoted by the addition of 0.25% polyvinyl alcohol and 0.75% carboxymethyl cellulose.
