Question

Define radius ratio. What is the ideal value for a tetrahedral void?

Prabhat Rajore · Accepted Answer

It is the ratio of the radius of the cation to the radius of the anion in an ionic crystal.the radius ratio of tetahedral is in between 0.225-0.732. Its ideal value is 0.225 for tetrahedral void.  - Wired Faculty
