Tungsten Copper Antimony Bismuth Alloy

In the tungsten copper antimony bismuth alloy, because radium is a shiny metal with activity chemical property, exposure to air can rapidly react with oxides and nitrides, then react with water to produce hydrogen oxide radium.

The infiltration method can be used to prepare tungsten copper antimony bismuth alloy, during the preparation process because of the radioactivity of Ra, Ra will volatilize, melting point and boiling point are lower. So it is not suitable to use the infiltration method. The performance and density of powder metallurgy products are lower, so the activation treatment of powder is to make it easy to sinter to obtain high density samples.

In order to prevent Ra metal oxidation and can be prepared in the atmosphere, therefore, Ra is usually regarded as impurity elements with Ra oxide instead of metal Ra alloy. Generally speaking, tungsten copper antimony bismuth alloy is prepared by the activated sintering of tungsten copper. In order to prevent the problem of radium oxidation, in the form of oxides to add tungsten copper antimony bismuth alloy.
