WebbChlorite Uses. Chlorite is a mineral with a low capacity for industrial use. It does now not have physical properties that make it suited for a specific use, and it does not contain materials that make it a target of mining. When found, chlorite is commonly in detail intermixed with different minerals, and the fee of separation could be excessive. WebbPHLOGOPITE, a mineral belonging to the group of micas (q.v.).

"WebbThe commonest types of mica used in insulation systems are phlogopite (K2 O·7MgOAl 2 O 3 · 6SiO 2 ·3H 2 O) and muscovite (K 2 O·3Al 2 O 3 ·6SiO 2 ·2H 2 O). As shown in Fig. 18.1, the structure of mica is complex: it contains aluminum and atomic layers of silicone, bonded together by oxygen atoms. " - Phlogopite cleavage

Webb1 sep. 2002 · On phlogopite lattice planes exposed by cleavage, numerous hillocks develop under ambient conditions. These protrusions have a similar appearance as those based on ART. However, they cannot be related to ART since, in contrast to them, they do not transform to etch pits. WebbIncremental-heating and laser-probe 40 Ar/ 39 Ar analyses were performed on phlogopite extracted from a garnet-lherzolite mantle nodule entrained by the Precambrian (1200 Ma) Premier kimberlite, South Africa. The spatial resolution of the laser probe has enabled the characterization of argon isotopic zoning in a single phlogopite grain.
