Abstract

A diphasic mullite gel has been synthesized by using Ludox and Al(NO3)(3) . 9H(2)O in ammoniacal solution. Both DTA and DDTA studies have been performed with a sensitive differential thermal analyzer system. Besides usual exotherm due to mullite formation, a pronounced exotherm between 800-1300 degrees C has been noted. Considering previous XRD data, it is explained as due to formation of Si-Al spinel phase, which is subsequently transformed exothermally at similar to 1320 degrees C to mullite.
