DOI: 10.1016/j.clay.2021.106094
Abstract: Abstract The phlogopite from the Qeganbulak vermiculite deposit in Yuli County, Xinjiang is selected as raw material and then transformes into phlogopite–vermiculite mixed-layer mineral and vermiculite through hydrothermal synthesis in the laboratory conditions. Furthermore, the… read more here.
