A Study on Preparation and Characterization of Mullite Coated Film by Sol-Gel Process
Optimal Mullite sol was synthesized by sol-gel process using Aluminium sec-butoxide(ASB), Tetraethoxysilane(TEOS) and then, Mullite films were dip-coated with various holding time in sol bath and heat-treated at 130$0^{circ}C$ above for crystallization. The thickness of coated film increased linearly with holding time in sol bath and average pore size was controllable within 20~30$AA$.
Key words: Sol-Gel, Mullite, Film, Pore Size
