Question

What is "occlusion"?

INORGANIC CHEMISTRY- S BLOCK ELEMENTS.

Answer 1

Here's what I find.

In chemistry, occlusion is the inclusion of one substance within another.

Occlusion can occur if precipitation or crystallization occurs rapidly.

If a crystal forms too rapidly, it may grow around the solvent, so that a "bubble" of solvent forms inside, even though it is not part of the crystal lattice.

For example, water may get trapped in pockets during the formation of silver nitrate crystals.
