“…The bene t of sol-gel method is higher purity and homogeneity, nal structure had ner grain size, heat treatment at low temperatures, and low cost can be considered in comparison with the solid state method for preparation of such structures [7].The advantage of Cordierite ceramics is very low coe cient of thermal expansion and high thermal shock resistance [8],high chemical stability and high mechanical strength [9].which are used in metallurgy, chemical industry , environmental protection and electronics, automobile [10],hot gas lters, membrane supports and membranes, catalysts and catalyst carriers. [11]recent research focusing on medical application of cordierite system ,especially in eld of 3D scaffold for bone replacement and cell growth on bioceramic [12][13] [14] [15].Stoyanova studied the crystallization temperatures of spinel-like cordierite, corundum, mullite, and MgAl 2 O 4 ,. The naturally occurring clay materials were used for the preparing of kieselguhr, and supports: bentonite,.…”
