Abstract

The effect of silica fume (SF) addition as a substitution of quartz on the thermo-mechanical properties and microstructure of traditional whiteware body compositions was studied. Noticeable improvement (10.0+0.5%) in the mechanical strength was observed on replacing quartz by 10% silica fume in whiteware body with the reduction of maturing temperature by 50 degreesC whereas addition of 25% silica fume reduced by 100 degreesC. The increase in strength has been attributed to the decrease in true porosity of the material as well as to the reduction of free quartz content in the composition. 34% Reduction of percentage thermal expansion at 600 degreesC was measured in the body mix containing 25% silica fume replacing quartz matured at 1150 C, compared to the reference body matured at 1250 degreesC. The lower maturing temperature of the body would be helpful to reduce the fuel consumption and thus reduce production costs. (C) 2002 Elsevier Science Ltd and Techna S.r.l. All rights reserved.
