Which risk increases substantially when calcium fluoride (CaF2) is heated beyond its melting point?

💡 Explanation

Increased electrical conductivity arises because, above the melting point, ionic dissociation leads to freely moving Ca2+ and F- ions; therefore, ion mobility produces conductivity rather than only solid diffusion, causing the increase compared to non-ionic scenarios.
