Influence of Sintering Temperature on the Properties of Porous Quartz Ceramics via the Atmospheric Pressure Sintering Method

Article Preview

Abstract:

Porous quartz ceramics were produced using river sand from the Yangtze River in China as the raw material via the atmospheric pressure sintering method. The influence of the sintering temperature on the density, the porosity, the porous structure and the outside shape of ceramics were investigated in this paper.The conclusions show that the sintering temperature increased, the microstructure of the samples changed accordingly and the density increased, while the porosity decreased, the micropores edge gradually become smooth. The optimum sintering temperature of porous quartz ceramics was obtained at 1100 °C as determined by an analysis of the performance price ratio of the porous quartz ceramics, the density is 1.25g/cm3, the porosity is 49.5%, the outside shape is regular, the micropore edge are smooth.
