Phlogopite mica

Segment plate, used as insulation between copper commutator segments on direct-current universal motors and generators, accounts for the primary use for built-up mica. Phlogopite built-up mica is preferred for these segments because it wears at the same rate as the copper segments. [Pg.291]

Charged layers of type (d) interleaved with ions. Replacement of one-quarter of the Si in talc and pyrophyllite layers gives negatively-charged layers which are interleaved with K ions in the micas phlogopite and muscovite (Fig. 23.17) ... [Pg.822]

Derivation From muscovite (ruby mica), phlogopite (amber mica), and pegmatite. Synthetic single crystals are grown electrothermally. [Pg.846]

Table 1. Observed absorption bands in cm and suggested band assignments for the synthetic micas phlogopite (Jenkins 1989), annite (Redhammer et al. 2000), muscovite and margarite (Langer et al. 1981) in the mid-lR lattice vibrational region. Horizontal lines band positions within 10 cm . [Al] = Al in octahedral coordination libr = librational mode. Table 1.

Geologists have computed surface reduction rates for certain carbonate rocks on the basis of the occurrence of resistant minerals in these rocks. Figure 7 shows aggregates of a mica, Phlogopite, projecting above the present stone surface. This reveals that the... [Pg.133]

Mica mI-ko [NL, fr. L, grain, crumb perhaps akin to Gk. mikros small] (1777) n. Any of a family of crystalline silicate minerals characterized physically by a perfect basal cleavage, consisting essentially of orthosilicates of aluminum and potassium. They occur naturally, mainly as the minerals muscovite (white mica), phlogopite... [Pg.617]

Porosimetry and SEM analysis demonstrate that type of refractory filler effects strongly morphology of the composite after ceramization. Only two samples, either containing mica (phlogopite) or wollastonite (WOL and MIC) are able to create nanoporous structure which can strongly improve thermal insulation of ceramic phase, what is very important from... [Pg.104]
