Catalyst-Free Synthesis of Mullite Nanosticks
The nonstoichiometric Al-rich single crystal mullite nanosticks were prepared by sol-gel method without any catalysts. The nanosticks are straight and uniform with a width of 300-350nm and length of 3-5m. The nanosticks’ growth direction is along . Detailed structural characterizations suggested that the growth of this novel nonstoichiometric structure was induced by the self-catalyzed process.
