Improvement of White Duekhla Clay properties by using Low-Density Polyethylene Fillers to use it in ceramic industries

The research was summarized in preparation and make samples of the ceramic body that are filled with Low-Density Polyethylene particles.The composite materials were manufactured by using ( Duekhla White Caly with Polymer particles) for purposes of improving the properties of clay for ceramic uses. The samples were prepared from The white Duekhla clay with fixed particle size (150µm) as a matrix and adding polymer powder particles (50µm) as fillers by different ratios in the range (2, 4, 6, 8, 10) %. Some essential materials such as feldspar and the fluvial sand. The results that were obtained from tests showed that higher contents of low-density polyethylene(LDPE) and that were added to the ceramic mixture gave good results and significant improvements for water absorbance resistance and less thermal conductivity. The mechanical properties of ceramic composites were improved by a higher ratio when adding (10%) of LDPE to ceramic composites. For example, the tensile strength was increased by an amount (175.5MPa) for the addition ratio (10%), compared with the pure sample (133MPa). The results of water absorbance and thermal conductivity decreased with increasing of the addition ratio for LDPE fillers. All obtained results indicated to the possibilities of improving the quality of the used clay in the ceramic industry for increasing the plasticity and disappear some disadvantages that were observed during the tests that were obtained on them
