Witryna18 mar 2024 · When NaCl is doped with SrCl 2, it leads to an impurity defect. Impurity defect is defined as a defect which arises when a foreign atom replaces a host atom at the lattice site. The process of adding impurities to the crystal is known as doping. In the given case, to maintain electrical neutrality, each Sr 2+ ion replaces two Na + ions. Witryna1 lis 2024 · In terms of theoretical treatments, the impurity and defect problem are also very similar, namely, one host atom on one particular lattice site is replaced by another atom that normally should not be there in the perfect lattice.

Witryna6 gru 2010 · The test electrolyte is investigated herein in NaCl because it is a simple approximation to atmospheric conditions and allows data to be compared with the large amount of data on commercial Mg alloys in the literature.
