Why Does Calcium Fluoride Exhibit a High Melting Point?
Calcium fluoride’s high melting point is due to its strong ionic bonding between calcium and fluoride ions. The electronegativity difference creates a powerful attraction, while its face-centered cubic crystal structure further enhances stability. In addition, these factors demand substantial energy to break the bonds, resulting in a high melting point of about 1,418°C (2,584°F). What…
