Which mechanism causes brittleness in ceramics containing high magnesium?

💡 Explanation

A large electronegativity difference introduces dominant Ionic bond character, because, rather than electron sharing, electrons transfer from magnesium to oxygen. Therefore, fewer available slip planes enhance the brittleness, rather than ductile behavior arising from metallic bonding.
