WebFirst found in Hector, California, hectorite may contain up to 1 – 1.2% lithium. Hectorite shows distinctive absorption features at 1400nm and 1900nm similar to other smectite clays including montmorillonite, and more distinctive features at 2300 and 2380nm. Other less distinct absorption features are sometimes found near 960nm and 1100nm. Web9 dec. 2024 · The understanding of the structural formula of smectite minerals is basic to predicting their physicochemical properties, which depend on the location of the cation substitutions within their 2:1 layer.
