Vermiculite - an overview ScienceDirect Topics

Chemical Characteristics— Vermiculite is a neutral clay, with a pH of 7.0–7.5 and low EC. This clay type contains two tetrahedral sheets for every octahedral sheet. Like the raw material, it has a permanent negative charge. Consequently, it has a CEC value of 15–21 cmol/kg and a buffering capacity for pH and cations.
