There are different methodologies to make volumetric ceramic bodies such as: uniaxial pressing, pressing, slips casting in plaster mold and filter pressing, however, there are different disadvantages when manufacturing thick ceramic slabs because all of them are influenced by the high costs of the equipment, the formation of density gradient and differential contraction in the drying stage. However, experimentation in this section was possible to increase the density and modulus of rupture of the samples, without much manufacturing cost. In such a way, when executing this research, a procedure was followed that began with the assembly of the system by hybrid pressure-vacuum collagen, consecutively slips were made, considering the amount of: solids (60%), water (40%), percentage of deflocculant (0.4% of Sodium Silicate) and the steel mold used for the samples. In addition, the casting respectively. pressure was 0.5 MPa gradually carried out by the compressor, taking a prolonged time of 20 minutes maximum for the filling of the six cavities of the mold, in parallel the vacuum suction is carried out being -0.5 MPa, then it was allowed to dry 72 h inside the mold, after that, the samples were removed from the mold to finally be tested for density (densification) and modulus of breakage, taking values of 2.31 g/cm3 and 4.6 MPa This method made it possible to manufacture kaolin samples of 30 x 50 x 12.7 mm with a homogeneous density by validating the surface of the samples with a stereoscope, resulting in pores with a diameter of 168,988 um for the samples by hybrid pressure- vacuum collage, influencing the possibility of manufacturing ceramic products with optimal properties.
