초록
The objective of this study is to present firstly the preparation of atomically ultra-homogeneous mullite precursors by ultrasonic spray pyrolysis technique and then to investigate the evaluation of mullite formation via calcination temperature and soaking time. At a temperature of as low as 500 o C for 15 days, the temperature was very close to the formation temperature of mullite (477 o C) is energetically possible; the structure of the precursor has been preserved as amorphous. It is possible to obtain single phase of mullite crystals at a temperature of 1000 o C without soaking time, while the crystallization required a temperature of 900 o C for 12 hours.
