<P>PROBLEM TO BE SOLVED: To provide a burning tool which is not deformed when burning an object and does not change the properties of an alumina ceramic molding element when burning the object. <P>SOLUTION: The ceramic-burning tool comprises a first aggregate having a particle size of 10-300 μm made of an electro-fused alumina and/or a sintered alumina, a second aggregate having a particle size of 10-300 μm made of an electro-fused mullite and a binder having a particle size of less than 10 μm made of a low soda calcined alumina, and does not comprise clay. The Al<SB>2</SB>O<SB>3</SB>/ SiO<SB>2</SB>ratio by weight is in the range of 85/15-95/5, and the aggregate/binder ratio by weight is in the range of 80/20-60/40, in total. <P>COPYRIGHT: (C)2003,JPO |
