Particle size influence of raw material grains on the characteristics of traditional ceramics

Abstract

Research has been conducted on the characterization of raw materials and traditional ceramics from clay, feldspar, quartz, and kaolin. In this research raw materials made with a grain size of 100 mesh; 150; 200 and 300 mesh, with the composition of the raw material clay: feldpspar: quartz: kaolin = 20: 30: 30: 20, plus 10% water, then printed with the Die Pressing method at a pressure of 5Pa for 10 minutes. The sample was dried, then the sample was burned in a stove to a temperature of 1000°C, hold for 5 hours. Characterization of ceramics at 300 mesh grain size showed that the density of ceramics tends to increase linearly with decreasing grain size, porosity and water absorption of ceramics tends to decrease linearly with decreasing grain size, and the ceramic has iron element Fe cubic structure with lattice parameter a = 2.87Å, AlKO2 compound, orthorhombic structure with lattice parameter a = 5.48Å, b = 11.03Å and c = 15.55Å; SiO2 compounds, trigonal structures, with lattice parameters a = 18.45Å and c = 7.48Å and aluminum elements, have cubic structures with lattice constants a = 4.04Å, with an average ceramic pore diameter of 3.199μm.
