Phase equilibria studies of the binary system Al_2O_3-SiO_2 have a very extended history for more than 80 years, yet, the melting nature of mullite, the only one compound in this system, is still ambiguous and controversial. In this paper, the published investigations on this problem are critically reviewed from the standpoint of crystal growth, and the conflicting problems involved in ordinal phase research methods are pointed out. It is suggested that the control of the solidification from this silicate liquid is the most important factor to avoid the misinterpretation of the results. Using the slow cooling float zone method, the phase diagram of this system is revised.
