Abstract :

This study aims to develop and characterize a low cost porous ceramic membrane from Moroccan natural resources by following a different approach. It consist in producing macro-porous ceramics through the dry compaction process by blending different proportions of raw clay with Moroccan natural phosphate which is highly rich with organic matter as a natural pore-forming agent. Thereafter, the compacted granulate produced as a result of the preceding technique is sintered at a high temperature of 1100 ├?┬░C. All samples undergo the characterization technique of TG-DTA, SEM, XRD, dilatometry and mechanical strength test. It was found that the microstructure and mechanical properties are strongly influenced by the amount of natural phosphate added (10-40 wt.%). Therefore increasing the amount of phosphate lead to increase of the open porosity and pore size while the flexural / tensile strength decreased accordingly to a diminution of raw clay amount. The largest average size of 5 micron pores with a porosity of 28.11%, tensile and bending strength of 11 MPa and 17.5 MPa respectively was determined based on a sample prepared of 60 wt.% clay and 40 wt.% of natural phosphate sintered at 1100├?┬░C.
