| 内容： | To prevent such phenomenon that titanium oxide and silicon oxide contained in an aluminum titanate sintered body are reduced by aluminum contained in molten aluminum alloy, and the erosion resistance is lowered, in a ceramic ladle. ! The ceramic ladle is mainly made of the aluminum titanate sintered body and is used for handling the molten aluminum alloy and has a film on the surface in contact with the above molten metal. This film is formed by mixing a ceramic material which does not react with the molten aluminum alloy and aqueous solution of 25-35 wt.% sodium silicate water glass of Na2O-nSiO2 (2.1≤n≤3.2), coating the mixed material in which 45-80 wt.% ceramic material is contained, and burning at 250-800°C. !
