HIGH-TEMPERATURE PHASE DEVELOPMENT IN ILLITIC CLAYS by
Five illitic clays were treated with various inorganic cations and heated to over 1400~ in a high-temperature X-ray diffraction furnace. The illite lattice undergoes dehydroxylation from 475-600~ and the resulting anhydrides begin to disappear at 850~ The major high-temperature phases formed from untreated illites are/?-quartz (1000-1300~ spinel (1000-1400~ and mullite (1150-1400 + ~ Minor amou...
متن کاملHigh Temperature Behavior of Dual Phase Steels
Dual phase steels with different martensite volume fraction and morphology were tensile tested at a temperature range of 25 to 5500C. Stress-strain curves of all steels showed serration flow at temperatures of 250 and 3500C, and smooth flow at the other temperatures. Both yield and ultimate tensile strengths increased with increasing testing temperature up to about 450<sup...
متن کاملCharacterization of Zeolite in Zeolite-Geopolymer Hybrid Bulk Materials Derived from Kaolinitic Clays
Zeolite-geopolymer hybrid materials have been formed when kaolin was used as a starting material. Their characteristics are of interest because they can have a wide pore size distribution with micro- and meso-pores due to the zeolite and geopolymer, respectively. In this study, Zeolite-geopolymer hybrid bulk materials were fabricated using four kinds of kaolinitic clays (a halloysite and three ...

متن کاملClassical Phase Fluctuations in High Temperature Superconductors
Phase fluctuations of the superconducting order parameter play a larger role in the cuprates than in conventional BCS superconductors because of the low superfluid density rs of a doped insulator. In this paper, we analyze an XY model of classical phase fluctuations in the high temperature superconductors using a low temperature expansion and Monte Carlo simulations. In agreement with experimen...
