Chapter II Solution Growth….<br />

From which it is clear that the induction period increases with increase in<br />

super-saturation level. The values of different critical parameters of nucleation,<br />

such as, the interfacial tension (γ) , the energy of formation (ΔG) and the radius<br />

of critical nucleus (r) are calculated using equations (2.21 ), (2.22) and (2.23),<br />

respectively. Equation (2.18) of the section 2.23 suggests a linear nature and<br />

a plot of ln τ versus 1/lnS 2 can be drawn.<br />
