Is Silicon Carbide bonded through covalent network?

From the image I'm looking at, I'm 100% sure it's covalent network bonding. Covalent network bonding is much stronger than covalent bonding, and seeing as how SiC's melting point is 2000+ degrees Celsius, that's the only thing that applies. It's not ionic, because the bonding is between two nonmetals (metalloids like silicon don't count as metals).
