| Abstract: | The molybdenum metalizing layer were produced on the surface of alumina ceramic at low temperature,using the precursor BaO-Al2O3-SiO3（BAS） glass of glass-ceramic as sintering additive.The effects of sintering temperature and BAS amount on the tensile strength were investigated,and the mechanism of metallization was also discussed.The results showed that the compacted molybdenum metalizing layer can be obtained at 1500～1550℃,and the tensile strength of jointed sample was over 260 MPa. |
