Tungsten Copper Points Density with Ce

The density of tungsten copper points -Cu20W80, will decline when you add rare earth (Ce)/rare earth oxides (CeO₂) to it. What’s worse, its density declines as the increase of additive amount. In theory, the density of Ce (6.77 g / cm³) and CeO₂ (7.10 g / cm³) lower than Cu20W80s’, which is 15.64g / cm³. So, the density of tungsten copper points’ density with Ce will be smaller when the additive amount of Ce or CeO₂ is larger.
The density of tungsten copper points decreases significantly if the amount of Ce is 1%; the density would not decrease substantially if Ce’s amount is from 1% to 3%; the actual density is relatively higher if the density is of 3 %( the optimum amount of Ce).
The density of Cu20W80 declining unevenly, and along with dramatic change trend. With the increase amount of CeO_2, its value reduces significantly. Nevertheless, the density value change relatively flat and upward slightly when its amount is from 5% to10 %. In a word, tungsten copper points with Ce is better, whose optimum addition amount is from 1% to3%.
