WebMar 28, 2024 · Sequence 1 was a two-step treatment representing a scenario in which biotite or phlogopite underwent some weathering before cesium addition. In this scenario, biotite or phlogopite was successively affected by simulated weathering and Cs + adsorption. In brief, 2.5 g of biotite or phlogopite was suspended in 0.25 L of 0.2 mol/L … WebAltered biotite, produced through hydrothermal or weathering processes, produces vermiculite, a porous material that is used as an insulating material in gypsum wall board and in other heat insulating applications. When heated, vermiculite will expand to many times its initial volume, in an accordion-like expansion of its layered structure ...
