On the Microstructure of Aluminum Titanate Powders Coated with Mullite Sol

摘要：

　　The mullite sol was prepared using tetraethyoxysilane (TEOS) as raw materials.Aluminum titanate (AT) powders were coated with the sol by dipping.The influence of the concentration of the mullite sol and pH value on the microstructure of the coated AT powders was studied.The results showed that AT powders are coated homogeneously and the thickness of the mullite film is about 0.15 μm when the concentration of the mullite sol is 0.18 mol.L-1 and pH value is 3.0.
