Thermal evolution of chromium oxide gels produced by "Sol-Gel" process
Written by sctunisie no comments"Sol-gel" process at room temperature is used to elaborate chronium III gels. The xerogel obtained after drying gel was characterised by different techniques : XR, DTA, TGA, and chromatography. The material was stayed amorphous until 400°C. Above this temperature it cristallizes to α Cr2O3 phase.
