How many kilograms of nickel must be added to 1.75 kg of copper to yield a liquidus temperature of 1300°c?

According to the copper-nickel phase diagram, the composition at the 1300°C liquidustemperature is about 43 wt% Ni.In order to determine the amount of nickel that must be added to 1.75 kg

Ni, it is necessary to use Equation 4.3a.If we letmNirepresent the mass of nickel required, then Equation4.3a takes the form

43 wt% Ni=mNi1.75 kg+mNi×100

And solving this expression formNileads tomNi= 1.32 kg

The reaction will shift to the right
