The physical properties of the red clay from the eski¸sehir region, turkey, and its usage in ceramic bodies

In this work, the properties of the red clay from Kayakent-Eski ¸sehir region in Turkey were investigated.The specific gravity 2.40 g/cm3, drying shrinkage 11.0%, the firing shrinkage 3.3%, the dry modulus of rupture 45.90 kg/cm2, the fired modulus of rupture 91.80 kg/cm2, the water absorption 9.0% and the loss of ignition 6.98% were found. As a research, this red clay was tested in the ceramic bodies as 20-30%. As a result of the researches, it was found that the number (1) and (2) body recaptures were suitable as a casting body. Number (2) body gave the more positive results. Upon firing, the body has comletely sinterized upon firing and the water of absorption was zero. The physical and casting properties gave particularly the good results and the standart products were obtained.
