Question

Among the following types of voids, which is the largest?

• A. Triangular
• B. Cubic
• C. Tetrahedral
• D. Octahedral

Answer 1

The correct option is B Cubic

On the basis of size:-

Cubic void > Octahedral void > Tetrahedral void > Triangular void .

Cubic voids can have radius ratio between 0.732 to 0.999, octahedral voids have a radius ratio between 0.414 to 0.732. Tetrahedral voids have a radius ratio between 0.225 to 0.414 and triangular voids have a radius ratio between 0.155 to 0.225.

Hence, the largest void is cubic void.
