A hybrid aluminosilicate gel composed of a relatively small amount of single-phase gel in a diphasic matrix forms when a diphasic gel of AlOOH and SiO2 is heated at 700°C for 7 h. The formation of mullite from this hybrid gel is a sequential convers

The reactivity of B4C with mullite was investigated under Ar and reductive atmospheres, respectively. The results indicated that B4C could coexist stably with mullite under Ar atmosphere below 1350°C, above which some reaction would occur to form Al
