Tile ceramic is formed by three constituent, they are clay, flux and filler. Clay has a function to give a plasticity to form the body and unfired strength in the formation and firing processes. Flux has a function to give the strength to fired product and filler has a function to control of the thermal expansion in fired body.<p> <br /> <br /> <br /> <br /> <br /> In this research the feldspar is used. The aim to use this material is to reduce the firing temperature which could reduce the production cost. The feldspath used in this research are orthoclase (potash feldspar) and albite (soda feldspar).<p> <br /> <br /> <br /> <br /> <br /> The objective of this research is to study the influence of orthoclase and albite in the ceramic tile mixture as a physical properties and mechanical properties on several fired temperature. Some studied physical properties are shrinkages, water adsorptions and hardness.<p> <br /> <br /> <br /> <br /> <br /> The research process was done by making a variation on the composition of feldspar only and the laboratory scale of firing temperature. Then the physical properties and mechanical properties of produced samples are measured.<p> <br /> <br /> <br /> <br /> <br /> The results show that the addition of orthoclase to ceramic tile makes a better physical property compare to the addition of albite. This result is different to the Dana and Das (2004) research. This research shows that the different is due to a different mixed grain size proportion between orthoclase and albite to be used and also the different between total alkaline of those two bodies. The proportions of those two bodies are 100% Kfeldspar and 100% Na-feldspar, of 6.7% and 5.4%. Grain size of the potassium feldspar smaller (15.9% has the grain size > 74&#956;m and 52.5% has the grain size < 53 &#956;m) compare to sodium feldspar (72.7% has the grain size > 74&#956;m and 20.31% has the grain size < 53 &#956;m). There is also found that the firing at the temperature of 1200 degrees C gives the smaller fluctuated range of the physical and mechanical properties compare to at the temperature of 1120 degrees C.
