A view on organic binder effects on technical properties of ceramic Raschig rings
Organic binders such as polyvinyl alcohol, carboxymethyl cellulose and Arabic gum are widely used to control the technological parameters required for green and sintered ceramic bodies.

| Sumario: | Organic binders such as polyvinyl alcohol, carboxymethyl cellulose and Arabic gum are widely used to control the technological parameters required for green and sintered ceramic bodies. An industrial ceramic Raschig ring composed of kaolinite, illite, pyrophillite and quartz minerals was separately mixed with different content of above binders and formed by extrusion process in the shape of Raschig ring. The dried specimens were sintered at 1270°C and the physicalmechanical characteristics of sintered bodies were evaluated by measuring bulk density, total and closed porosities and compressive strength. In addition, the effect of binder type and amount on reliability of ceramic Raschig rings was evaluated by computing Weibull modulus. The obtained data exhibited optimum strength and reliability in presence 0,75 wt.% carboxymethyl cellulose. |
