Vermiculite

The lower charge per formula unit of vermiculite, compared to micas, allows the interlayer to open, allowing exchangeable cations to move in and out. The layer charge of 0.9–0.6 per formula unit gives vermiculite a high cation exchange capacity, but a strong affinity for weakly hydrated cations such as K +, NH 4 + (ammonium), and Cs + (cesium

What Is Vermiculite | Types Of Vermiculite And How To Use Them?

Vermiculite is a silicate material that is used in horticulture as a growing medium. The name originates from the word vermiculture which means to breed worms.
