Tubular Ceramic Foam Via Polymeric Sponge Method

[Full Text]

Index Terms: compressive strength, density, porosity, sintering temperature, tubular ceramic foam.



Abstract: Tubular ceramic foams were prepared by using natural clay as starting material and 120 ppi polyurethane foam as template via polymeric sponge method. Samples were sintered with different temperatures from 1200°C to 1280°C. The result shows that 1250°C is the ideal sintering temperature where the highest compressive strength of 1.980MPa at 47.31% porosity is obtained. The highest value in compressive strength and the lowest percentage in porosity are attributed to the higher apparent density and crystallinity. These results lend support to the idea that the sintering temperature is important for the processing of tubular ceramic foam.
