摘要
Aluminosilicate diphasic gel was synthesized by using inorganic salts and characterized by chemical analysis, Fourier transform infrared spectroscopy spectroscopic studies and surface area and bulk density measurements. The gel powder was compacted with nickel oxide additive in three different ratios (wt/wt). Differential thermal analysis of gel samples with additive and without additive was carried out at four different heating rates and for each sample, the activation energy of mullitization was calculated using Kissinger equation. The microstructure and phase analysis were carried out by scanning electron microscopic and X-ray diffraction studies. Observation showed that nickel oxide favored the mullitization process.
