We describe the preparation of clay with the incorporation of sawdust with different sieving (0.425, 0.84, and 1.41 mm) using a furnace at 890 °C by 9 h. After burned, some samples were immersed in a solution of Ag nanoparticles. The samples were analyzed to obtain their physical, structural, and morphological properties. The densities for each sample were obtained in the range of 3.44 and 2.673 (g/ml) and the volumetric absorption between 16.06 and 45.11%. The XRD pattern shows the four main characteristic phases of the clay as quartz (SiO2), Al2O3, Fe2O3, and TiO2. The morphology of the samples was analyzed by scanning electron microscopy (SEM) observing various pore sizes depending on the sieves used for sawdust.
