- This research aims to make clay and Pahae natural kaolin based porous ceramic using hull of rice ash as additive and to study the influence of variation of composition of hull of rice additive with clay and Pahae natural kaolin to the characteristics of porous ceramic on sintering temperature 900°C, 1000°C, and 1100°c. The raw material of this ceramic consists of clay and Pahae kaolin mixing with the addition of hull of rice ash as additive in the percentage 0%, 5%, 10% and 15% and then sintering of each admixture in temperature of 900°c, 1000°C and 1100°C. This aims to get the better admixture by burning and to study whether is there an increasing of physical characteristics of the porous ceramic material, i.e. burning wastage, porosity, density, hardness and XRD (X-Ray Diffraction) analysis. Based on the results of research indicates that the physical characteristics of clay and Pahae natural kaolin based porous ceramic with hull of rice ash as additive is : the burning waste on sintering temperature 900°C-1100°C is (18.91 - 23.31)%, the porosity value is (27.80- 56.94)%, density value is (1.33 - 1.71) gr/cm3, hardness value is (8.78 - 12.87) kgf/mm2 and the results of XRD analysis indicates that the dominant phase on ceramic is Aluminium Silicate Hydroxide [Al2Si2O5(OH)4].
