Question

When the mixture of silica and coke is heated in an electrical furnace, silicon carbide is formed instead of silicon. What is the reason?

Answer 1

When the mixture of silica and coke is heated in an electrical furnace, silicon carbide is formed instead of silicon. This is because less amount of silica or more amount of coke is used. If we use excess of silica or less amount of coke, then we will get silicon.
