The Mechanism of the Deformation of Clay
Cambridge University Press (CUP) - Tập 2 - Trang 480-491 - 1953
W. R. Buessem
AbstractKaolinite-water mixtures, containing from 23 percent to 33 percent water, were subjected to compression plastometer tests and their plasticity was studied by means of the calculated strain-stress functions. X-ray diagrams taken of the compressed samples showed that an oriented texture developed during the compression, i.e., the basal planes of the flaky cla...... hiện toàn bộ
The Mechanism of Dehydration of Mg-Vermiculite
Cambridge University Press (CUP) - - 1955
G. F. Walker
AbstractThe hydrated Mg-vermiculite lattice contains double sheets of water molecules interleaved with silicate layers. In the fully hydrated condition, each water sheet is arranged in a regular hexagonal pattern and the interlayer cations are located midway between water sheets in octahedral coordination.Release of water molecules from interlayer ...... hiện toàn bộ
Flow Properties of the Kaolinite-Water System
Cambridge University Press (CUP) - Tập 3 - Trang 549-556 - 1954
F. H. Norton
For the last 20 years, the Ceramic Division at the Massachusetts Institute of Technology has been carrying on basic work with the kaolinite-water system. The results have been published from time to time in the Journal of the American Ceramic Society under the title of “Fundamental Study of Clay.”At the start, it was realized that natutal clays w...... hiện toàn bộ
A Discussion of the Water Content of Vermiculite
Cambridge University Press (CUP) - - 1958
William Bradley
AbstractSelected chemical and diffraction analyses from the literature, supplemented by thermal and thermogravimetric analyses and infrared absorption observations, are utilized to construct a rational model of the water arrangement in natural vermiculites.A super cell is arranged by simple modification of the Hendricks water nets to accommodate th...... hiện toàn bộ
Distribution of Clay Minerals and Ion-Exchange Capacity in Some Sedimentary Materials
Cambridge University Press (CUP) - Tập 2 - Trang 264-276 - 1953
John C. Hathaway
AbstractThe cation-exchange capacity of the clay fraction was determined in 67 samples of various types of sedimentary materials, and the clay minerals were identified from x-ray diffractometer patterns of oriented aggregates. The probable quantitative clay mineral composition was established for each sample assuming a comparable degree of crystallinity for the cla...... hiện toàn bộ
Current Progress in Silicate Structures
Cambridge University Press (CUP) - Tập 6 - Trang 18-25 - 1957
William Bradley
AbstractAttention is called to the value to be derived from application of diffraction analysis of modern grade to specific, familiar, approximately known crystallizations. Features consequent to ordering of coordination polyhedra of differing sizes in layer structures are discussed, and their bearing upon relations between lattice parameters and chemical compositi...
Flow Properties of Dilute Montmorillonite Dispersions
Cambridge University Press (CUP) - - 1957
W. T. Granquist
AbstractA viacomotrio study of dilute montnioritlonite dispersions, using lor tho most part dilution-typo capillary viscometers supplemented by a falling-head capillary viscometer, has involved a determination of the concentration dependence of viscosity of such dispersions in both distilled and electrolyte-containing water. The resulta of the study have been inter...... hiện toàn bộ
Oxidizing Power of the Surface of Attapulgite Clay
Cambridge University Press (CUP) - - 1963
John G. Miller
AbstractIt has been demonstrated that ferric iron is the principal source of the oxidizing action of the surface of attapulgite clay. The extent of oxidizing action in a given time (the oxidizing power) has been determined as a function of the temperature of calcination of the clay in the range 100–900°C.The oxidizing power was measured with TiCl... hiện toàn bộ
Altered Siliceous Volcanics as a Source of Refractory Clay
Cambridge University Press (CUP) - - 1956
L. B. Sand
AbstractIn the intermountain states, a region deficient in kaolinite and alumina clays, there is an increasing demand for refractory clay. In this arid region residual kaolins are not developed in quantity from feldspathic intrusives. Glassy, siliceous extrusives alter commonly to mont-morillonite of the montmorillonite-beidellite series. Zeolites, principally anal...... hiện toàn bộ
Orientation and Packing of Aliphatic Chain Molecules on Montmorillonite
Cambridge University Press (CUP) - Tập 9 - Trang 546-556 - 1960
G. W. Brindley, Reinhard W. Hoffmann
AbstractAliphatic chain molecules may be adsorbed on montmorillonite surfaces with the zigzag of their carbon chain either parallel or perpendicular to the surface. These orientations are designated αII and αI, respectively. Fourier syntheses have too few terms to distin...... hiện toàn bộ
