Winchite and the actinolite–glaucophane miscibility gap
Nature, 1982Leake et al.1 have recently emphasized the apparent scarcity of winchite s.l., NaCa(Mg, Fe2+)4(Al, Fe3+) [Si8O22/(OH)2] (ref. 2), an amphibole intermediate in composition between the glaucophane–riebeckite series of high-pressure blueschists and the tremolite–actinolite series of lower-pressure greenschists.

On the miscibility gap of MnxCr3−xO4 spinels
Solid State Communications, 1977Abstract Annealing experiments on Mn x Cr 3− x O 4 system were carried out in order to determine the miscibility gap boundaries. The coexisting phases were determined by X-ray analysis. An influence of the oxygen non-stiochiometry was investigated and the boundaries of three phase regions (Cr 2 O 3 -cubic spinel-bixbyite and cubic spinel ...

Narrowing of the palladium-hydrogen miscibility gap in nanocrystalline palladium
Physical Review B, 1993In situ x-ray-diffraction studies of the hydriding behavior of coarse-grained and nanocrystalline palladium samples at ambient temperature are descibed. A previously observed narrowing of the miscibility gap in nanocrystalline palladium was reproduced.

Berichte der Bunsengesellschaft für physikalische Chemie, 1987
AbstractThe dependence of the upper and lower critical solution temperatures Tc of the systems (1) oxolane + water, and (2) 2‐butoxyethanol + water on the mole fraction XEl of dissolved 1‐1, 2‐1, and 3‐1 electrolytes has been investigated. The material stability of the homogeneous state of both systems is extremely sensitive to small electrolyte ...

Solidification of alloys with a liquid miscibility gap
, 2011 The solidification of alloys with a liquid miscibility gap, called monotectic alloys, is puzzling since decades especially compared to eutectic solidification to which they seem very similar.

Delimitation of the Hematite-Ilmenite Miscibility Gap
Geological Society of America Bulletin, 1973Note: This paper is dedicated to Aaron and Elizabeth Waters on the occasion of Dr. Waters' retirement. Recent analytical data on the compositions of natural hematite-ilmenite solid solutions suggest that the miscibility gap of Carmichael (1961) cannot be correct. Attempts to redetermine the miscibility gap under hydrothermal conditions have been only

On the miscibility gap in monazite–xenotime systems
Physics and Chemistry of Minerals, 2007The regular solid solution model has been applied to solid solubility in the monazite–xenotime systems and is verified against the available experimental data for LaPO4–YPO4 and CePO4–YPO4 systems. The model is then used to predict the miscibility gaps in a number of other monazite–xenotime systems.

Recueil des Travaux Chimiques des Pays-Bas, 1960
AbstractThe miscibility gap was determined by measuring the cloud point of a number of water‐phenol‐CETAB mixtures.The position of the tie‐lines was established at 20°, 40° and 48°, by analysing the coexisting phases.

Journal of Phase Equilibria, 1993
The thermodynamics of phase diagrams with a miscibility gap and a congruently melting compound and phase diagrams with two miscibility gaps are treated using the Hoch-Arpshofen solution model and the Schottky- Wagner disorder model. We extended the Schottky-Wagner disorder model to the liquid phase. In phase diagrams with two miscibility gaps, a liquid
