Studying on Hot Pressure Casting Process of CaZr_0.9In_0.1O_3-α Tubes for Hydrogen Sensor in Aluminum Melt

Abstract:

The relationship of the powders and binder system and forming process on the quality of the U-shaped proton conducting CaZr_0.9In_0.1O_3-α tubes was studied. The results showed that defect-free green bodies can be obtained under the conditions of the wax slurry containing 87.8% (mass percentage, the same below) proton conductor powders, 11% paraffin wax, 1% beeswax and 0.2% oleic acid, the wax slurry and mold temperature at 73°C and 30°C, the casting pressure and time at 0.5MPa and 15s. A reasonable wax removing schedule about the green bodies was put forward. At last the sintered samples were characterized by higher density and less shrink rate and distortion.
