Magnesium aluminate spinel (MgAl2O4) composites were prepared by mixing the commercial Alumina and Magnesium Oxideas starting raw materials. Titanium oxide (TiO2) and Zirconium oxide (ZrO2) were used as additives. The mixtures wereprepared as by milling of five different combinations using zirconia balls for 1 hour each. Then Cold Isostatic Press (CIP) at200 MPa pressed the batches. The material properties, such as porosity and density, and thermal expansion of the compositeswere characterized by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), and the dilatometer measurements. MgAl2O4 ceramic composites are composed of spinel and garnet structures. The thermal expansion coefficients (CTE) ofMgAl2O4 composites with and without TiO2 and ZrO2 additives under different temperature condition (25 oC to 1,300 oC) werecharacterized for spinel thermal expansion study and it shows that the comparison between the five different samplecombinations at 1,300 oC, adding TiO2 or ZrO2 by small percentage gives the lowest CTE (9.89E-06, 1.02E-05) respectively,but increasing ZrO2 increases the CTE.
