A highly stable ?-Al2O3 and in particular, to a highly stable mesoporous ?-Al2O3, stabilized by a small doping of R3+ cations where R is selected from Eu3-, La3-, Tb3- and Cr3+or other additive adapted to retain the mesoporous structure and porosity when exposed to elevated temperatures The highly stabilized ?-Al2O3 structure would be stable at high temperature having a mesoporous structure throughout such as about 1400 K and at the same time would be cost-effective to obtain The ?-Al2O3 also achieves a desired porosity of 40%, useful for gas sensors, catalysts, surface coating, phosphors and other applicationsAlso disclosed is the process for simple and cost-effective manner of manufacture of such stabilized ?-Al2O3 in a mesoporous structure The method of manufacture of the ?-Al2O3 is environment friendly and require no additional reagent Importantly, the method of providing of ?-Al2O3 would require very small amount of doping to stabilize ?-Al2O3 phase over an extended range of temperature to 1400 K and involve simple and fewer steps.
