    Properties of ceramic products are related to initial characteristics of raw materials, so it is important to study them to obtain a quality product. In this study, aimed to evaluate clay composition and study physical-mechanical behavior of different raw materials used in production of ceramic tiles, allowing their analysis and processing in a simple, controlled and standard. Six unidentified raw materials donated by a ceramic coating industry from Cabo de Santo Agostinho were used. The samples were benefited and characterized per X-ray diffraction (XRD), Energy-dispersive X-ray spectroscopy (EDX) and sedimentary particle size. After, raw materials were uniaxial pressing and subjected to controlled burning at 1000 ºC/ 1h with rate of 5ºC / min. Then, properties were evaluated per of linear shrinkage, water absorption, apparent porosity and flexural strength. The samples presented crystalline phases of kaolinite, quartz, mica and smectite, besides of alkaline oxides. The mechanical properties of samples showed the highest plasticity index (18%) and maximum strength went MP1 and MP6, 18% and 20.45 MPa, respectively. Thus, the raw materials presented physical properties for use in various applications in ceramic tile, such as ceramic.
