Dielectric properties of iron-bearing trioctahedral phyllosilicates
Physics and Chemistry of Minerals, 1997Measurements of the real part of conductivity (σ′) and dielectric function (ɛ′) were performed on large crystal flakes of biotite (Moen) and vermiculite (Benahavis), at variable frequencies (0.1 to 1000 kHz) and as a function of temperature (300 ...

Eu(III) coprecipitation with the trioctahedral clay mineral, hectorite
Clays and Clay Minerals, 2006AbstractVarious secondary phases formed during alteration/dissolution of HLW (high-level nuclear waste) borosilicate glass represent a significant retention potential for radionuclides including divalent actinides. The trioctahedral smectite, hectorite, Na0.7[Li0.7Mg5.3Si8O20(OH)4], is one of the secondary phases identified within the alteration layer ...

Hydrothermal Synthesis of Low Layer Charge Trioctahedral Smectite
2021Smectites are widely used in (geo-) technical applications and are important components of soils. A definition gap exists between the uncharged non-swellable pyrophyllite and talc ( = 0) and the low charged swellable clay minerals (smectites) with 0.2 0.6. Furthermore, no reliable measurement method exists for < 0.2.

Salt Displacement of Acid‐Treated Trioctahedral Vermiculites
Soil Science Society of America Journal, 1967Abstract Freshly prepared and 30‐day‐aged samples of HCl‐treated trioctahedral vermiculites from Libby, Montana (L) and northeastern Transvaal, South Africa (S) were leached with 1 N or more dilute solutions of NaCl, KCl, CaCl 2 , or ...

The present study presents a generalized procedure to accurately identify trioctahedral 1:1 layer silicates. The reciprocal space (RS) sections were obtained by the precession method by “unwarping” frames that were recorded using diffractometers with ...

Dielectric Properties of a Di-trioctahedral Chlorite: Cookeite
Transactions of the Indian Ceramic Society, 1988Temperature and frequency variations of the dielectric constant (K), loss (tan δ) and conductivity of a di-trioctahedral chlorite (cookeite) were measured in the temperature range 30°—400°C and frequency range 102—107 kHz. The variational patterns of these parameters of cookeite have been compared with those of ripidolite, a tri-trioctahedral chlorite ...

Compositions of trioctahedral micas in the Cornubian batholith
Mineralogical Magazine, 1988AbstractNew major and trace element chemical analyses of trioctahedral micas of the Cornubian batholith emphasize their enrichment in a ‘trace-alkali element’ association (Li, Rb, Cs, F, Nb, Mn) and their deficiency in a ‘femic element’ association (Zr, Ce, Th as well as Mg and Ti) compared with micas from many other granite suites, although there are ...
