Coke

Vedclass · Answer

(C) In the Serpeck's process,bauxite $(Al_2O_3 \cdot 2H_2O)$ is heated with coke and nitrogen at $1800 \ ^\circ C$ to form aluminium nitride $(AlN)$.$Al_2O_3 + 3C + N_2 \rightarrow 2AlN + 3CO$.Silicon dioxide $(SiO_2)$ is an impurity present in bauxite. It is removed by reacting with coke to form silicon carbide $(SiC)$ or by reacting with $CaO$ if present as a flux,but in the specific context of Serpeck's process,the reduction of $SiO_2$ by coke is the primary mechanism to eliminate it as volatile $SiO$ or $SiC$.

Which of the following is used to remove silicon dioxide in the Serpeck's process for the purification of bauxite?
