Lithium smectite
WebLithium saturation can be used to distinguish montmorillonite from beidellite. The method described below was modified by Schultz (1969), but is commonly referred to as the Hofmann-Klemen test. If the smectite present in a Li-saturated sample is beidellite, the basal smectite peak will still expand after treatment with ethylene glycol. Web15 dec. 2005 · We used hydrothermal experiments at 300°C, 100 MPa, to speed up the reaction of smectite to illite that normally occurs during slow (10–100 Ma) sediment …

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. WebSmectite.

Smectites are commonly used in very diverse industrial applications. In civil engineering works, it is routinely used as a thick bentonite slurry when excavating deep and narrow trenches in the ground to support the lateral walls and to avoid their collapse. It is also used as mud for drilling fluids. Smectites, more commonly called bentonite, are candidate as buffer and backfill materials to fill the space around high-level radioactive waste in deep geological repositories.
