PROBLEM TO BE SOLVED: To provide a material for making an electronic part by sintering capable of preventing for an exfoliation of a zirconia layer covered on the surface of a substrate, a usual material for making an electron part, and low strength of zirconia layer. The material for making the electronic part by sintering is produced economically. SOLUTION: The material for making the electronic part by sintering is bound by a coarce zirconia powder of which the average particle diameter is 30-500 μm, a fine zirconia powder of which the average particle diameter is 1-10 μm and a partial melting binder which consists of more than two kinds of metal oxides. When the coarse zirconia powder is sintered each other or the coarse zirconia powder and the fine zirconia powder are sintered with a partial melting binder which consists of yttrium oxide and aluminum oxide, the high efficient material for making the electronic part by sintering is produced. And then the binding strength and the adherence of zirnonia layers are much improved. |
