Fig. (6) Decrement in electrical conductivity of 1.5 × Sr-SBF
(grey) and 1.5 × Zn-SBF (black) through various soaking periods
with respect to the mother solution. (Where σm is the conductivity
of the mother solution and σn is the conductivity of respective time
interval). The drawn curve represents the polynomial fitting of
fourth order to the obtained results.
