<P>PROBLEM TO BE SOLVED: To provide a high melting point metal material having a function to prevent an object to be treated from melting and adhering when sintering a MIM product, and having a great economical effect since energy used for heating and cooling can be substantially saved by thinning its board thickness, and to provide its manufacturing method, and a board for sintering by using it. <P>SOLUTION: In this metal material having one kind of molybdenum, tungsten, a molybdenum base alloy, and a tungsten base alloy, an oxide layer to which a mixture obtained by mixing at least one kind or two or more kinds of aluminium, silica, zirconia, yttria, titania, magnesia, and calcia is welded is provided on at least one face of the above metal material. The oxide layer is provided with an oxide coated layer having no exposed bedding material by covering at least the one whole surface. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
