Is silicon carbide ( SiC ) an ionic or covalent bond

Question : Is silicon carbide ( SiC ) an ionic or covalent bond ? Answer : silicon carbide ( SiC ) is a Covalent bond What is chemical bond, ionic bond, covalent bond? Chemical bond A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds.

Reaction Bonded Silicon Carbide (RBSC)

Mar 06, 2001· Reaction bonded silicon carbide is made by infiltrating compacts made of mixtures of SiC and carbon with liquid silicon. The silicon reacts with the carbon forming silicon carbide. The reaction product bonds the silicon carbide particles. Any excess silicon fills the remaining pores in the body and produces a dense SiC-Si composite.
