Abstract

Stabilization of θ{symbol}-alumina phase by silica was studied in nanocomposite (diphasic) alumina-silica gels by XRD and BET surface areas measurements. Five wt.% of silica (22 nm particles) increased the crystallization temperature of θ{symbol} to α-alumina by about 100°C from boehmite (10 nm particles) derived alumina. Stabilization of θ{symbol}-alumina was caused by the formation of intimate contact (Al-O-Si) between components by diffusion of silica into the defect alumina structure.
