Why Does Silicon Carbide Have A High Melting Point? - …

Its melting point is 2730 degree C, which is quite high. The reason for the high degree in temperature was that despite being covalently bond, it also has a ionic bond with it, which positive and negative ions attracting each other. Why the melting point of diamond is higher than that of silicon carbide?
