← ScienceWhich outcome occurs when grain boundaries severely disrupt a crystal lattice?
A)Reduced thermal and electrical conductivity✓
B)Increased magnetic domain alignment
C)Enhanced single-crystal transparency
D)Higher superconduction critical temperature
💡 Explanation
Reduced conductivity occurs because electron scattering increases due to disruptions of the crystalline lattice periodicity by grain boundaries which impede electron (and phonon) transport via increased phonon scattering, therefore, conductivity decreases, rather than properties improving, as grain boundaries act as defects.
