Synthesis of nickel aluminates spinel on silica oxide
Abstract
Nickel aluminates spinel NiAl204 in the silica glassy matrix was prepared through insitu sol-gel reaction. The influence of temperature and the molar ratio of metals to Si on the formation of the spinel were investigated. The DTA, TGA and XRD analyses showed that NiAl204/Si02 was completely produced at 800oC. The surface properties of the synthesized spinel were identified by nitrogen adsorption-desorption method
