Abstract

Porcelains made of ball clay, feldspar, kaolin and quartz were investigated to study the effect of adjustment of quartz content on the bending strength. These raw materials are mixed by ball milling and formed by slip casting. The bending strength for Batch A is the highest which is 22.51 MPa followed by batch C which is 12.89 MPa and batch B, 8.21MPa. Batch A with the highest quartz content results in lowest reading of total linear shrinkage after drying and sintering which is 24%. A decreasing content of quartz leads to increasing shrinkage. The shrinkage of porcelain increases from bisque firing temperature of 900°C to final sintering temperature of 1250°C. The analysis methods are done to determine the morphologies of the porcelain ceramics using Scanning electron microscopy (SEM) and X-Ray Diffraction (XRD). In XRD analysis, the existence of quartz as SiO2 is more compared to the existence of mullite in Batch A meanwhile in SEM analysis, the amount of pores in Batch A is less than Batch B and batch C. These analyses have provided the information that increasing in quartz content leads to decreasing in pores amount in a porcelain body and this finding is then correlated to the strength and shrinkage of the body.
