Choose an option
Show full solutionCorrect option: B
Correct answer
Bhcp lattice - B, Tetrahedral voids - A
Step-by-step explanation
A2B3 has HCP lattice
If A form HCP,
then of THV must occupied by B to form A2B3
If B form HCP, then of THV must occupied by A to form A2B3
If A form HCP,
then of THV must occupied by B to form A2B3
If B form HCP, then of THV must occupied by A to form A2B3
