phase diagramalpha-quartzbeta-quartztridymiteAn internally consistent data set on the thermodynamic properties of the silica polymorphs stable up to 15 GPa (-quartz, -quartz, tridymite, cristobalite, coesite, and stishovite) and the liquid phase is presented. The data set was produced through a ...
The phase diagram for a simple binary system A–B without any binary phases is shown in Fig. 3.1. Compositions may be expressed as either mole % or weight %. At low temperatures a physical mixture of A and B is represented. Where two or more phases coexist, they are said to be ‘com...

For example, global anisotropy introduced via uniaxial compression of aerogel might stabilize the axial state, which is called the A -phase in bulk superfluid He3 . Here, we present measurements of the phase diagram of superfluid He3 in a 98% porous silica aerogel by using transverse acoustic ...
Therefore, it is a necessity to consider hydro-chemical characteristics of subduction zone fluids (SZFs) with respect to reactions and stabilities of subducting minerals. Salt and gas such as NaCl and CO2 are important components of the SZFs, together with dissolved silica, to affect the ...
However, experimental determination of the nano-phase diagram is scarce since calorimetric measurements remain quite challenging at the nanoscale. Based on the size- dependent cohesive energy model, we developed a unified nano-thermodynamic model to investigate the effects of the size, shape, and ...
