The image of impurity resistivity for two phase impurities is shown below. To calculate impurity resistivity for two phase impurities, four essential parameters are needed and these parameters are Resistivity of Phase α (ρα), Resistivity of Phase β (ρβ), Volume Fraction of Phase α (Vα) and Volume Fraction of Phase β (Vβ).
The formula for calculating impurity resistivity for two phase impurities:
ρi = ραVα + ρβVβ
Where:
ρi = Impurity Resistivity for Two Phase Impurities
ρα = Resistivity of Phase α
Also, ρβ = Resistivity of Phase β
Vα = Volume Fraction of Phase α
Vβ = Volume Fraction of Phase β
Let’s solve an example;
Find the impurity resistivity for two phase impurities when the resistivity of phase α is 8, the resistivity of phase β is 6, the volume fraction of phase α is 4 and the volume fraction of phase β is 2.
This implies that;
ρα = Resistivity of Phase α = 8
ρβ = Resistivity of Phase β = 6
Vα = Volume Fraction of Phase α = 4
Vβ = Volume Fraction of Phase β = 2
ρi = ραVα + ρβVβ
So, ρi = (8)(4) + (6)(2)
ρi = (32) + (12)
ρi = 44
Therefore, the impurity resistivity for two phase impurities is 44 Ωm.
