Conversion of Atomic Ratio and Mass Ratio
发表于:2018-07-09 20:36 分享至:

It is known that the atomic weight of A metal is m,

The atomic weight of B metal is n.

 

The atomic ratio is calculated as the mass ratio A(x)B(y) of the A(h)B(k) alloy (The premise is that X, Y are the atomic percentage of A, B metal, atomic % is the content, X + Y = 100), the h, k value is calculated as follows:

h=100*x*m/(x*m+y*n)

K=100*y*n/(x*m+y*n) (ie k=100-h)

 

For example: It is known that the atomic weight of A metal Ti is 48.

The atomic weight of B metal Al is 27,

 

Calculate the mass ratio of Ti70Al30 (atomic ratio) alloy (70, 30 is the atomic percentage of titanium, aluminum, respectively). The corresponding mass ratio of Ti(H) to Al(k) is calculated as:

 

h=100*70*48/(70*48+30*27)=336000/4170=80.58
k=100*30*27/(70*48+30*27)=336000/4170=19.42

 

That is, the mass ratio (wt%) of the alloy with an atomic ratio (at%) of Ti70Al30 is approximately Ti80Al20.

 

The conversion method for the atomic ratio and mass ratio of the ternary alloy and the multicomponent alloy is the same as the conversion method for the binary alloy.
