After pressingTungsten-molybdenum alloy or molybdenum-copper mixed powders , the liquid-phase sintering at 1300-1500 °. This material prepared by uniformly bad, there are more closed the gap, the density is usually less than 98%, but by adding a small amount of nickel activated sintering, mechanical alloying method for reducing or Ultrafine oxide nanopowder can improve the sintering activity, thereby increasing tungsten, copper, molybdenum, copper alloy density. But the nickel activated sintering cause the material conductivity, thermal conductivity decreased significantly, the introduction of mechanical alloying impurities will reduce the material conductivity; oxide powders were prepared by reduction, process cumbersome, inefficient production, it is difficult production.
