← ScienceWhich consequence results when compressive stress introduces dislocations in ionic cement?
A)Increased ionic conductivity cracking✓
B)Enhanced polarization within crystalline domains
C)Reduced electron bandgap width
D)Exacerbated hydrolysis by absorbed moisture
💡 Explanation
Increased ionic conductivity occurs because the applied stress leads to increased defect density via the Frenkel Defect mechanism, increasing mobile ion populations; therefore, causing increased drift and cracking initiation, rather than enhancing polarization or reducing the bandgap.
