Fig. 5 Morphologies of the products obtained at 1173 and 1473 K
Fig. 6 Percentages of mass
loss obtained at different
reaction temperatures
Furthermore, the contents of Pb and Zn in the products were also determined
by ICP. As shown in Fig. 7, the content of Pb in the products decreased obviously
when the reaction temperature increased. The saturated vapor pressure of lead oxide
increased with the increase of temperature [10]. Therefore, the element of lead could
evaporate from the products in the form of lead oxide at the higher reaction temperatures. The two reasons discussed above ultimately led to the increase of the
percentages of mass loss.
