Vermiculite Nanomaterials: Structure, Properties, and Potential
The X-ray diffraction patterns of the South African vermiculite with high potassium content in the interlayer space (K 0.53) showed the value d = 1.45 nm corresponding to the vermiculite and additional peaks with d = 2.52 nm, d = 1.26 and d = 1.205 nm, which resulted from a biotite-vermiculite mixed-layer mineral [17].
