ALUMINUM TITANATE CERAMICS-MADE MEMBER FOR IMPROVING NON-WETTABILITY AGAINST ALUMINUM ALLOY MELT AND MANUFACTURING METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To impart non-wettability and its durability against aluminum alloy melt of aluminum titanate ceramics.;SOLUTION: To at least a region in contact with the aluminum alloy melt of an aluminum titanate ceramics-made alluminum alloy melt contact member, an Al₂O₃ film and/or an MgAl₂O₄ film substantially not containing Si and capable of controlling the diffusion of Al or Mg in the alluminum alloy melt and of silica in the aluminum titanate is formed. Thereby, excellent non-wettability and durability against the aluminum alloy melt are exhibited.;COPYRIGHT: (C)2004,JPO
