Alkali-rich lead glass with working range at room temperature

I understand that the glass transition temperature (above which it is considered a super-cooled liquid) is quite far below the liquidus of the corresponding crystalline mixture. In the paper, "...

Eutectic temperatures of multicomponent metal carbides

Some carbides do not melt at atmospheric pressure. At high enough temperature, metallic element is in vapor phase. Experimentation with these systems is complicated because of their high melting or ...

Phase Diagram Vertical Lines

We had to create a phase diagram of H2O and NaCl. My professor mentioned that the vertical line I’ve encircled is at the weight % of 61.9. I was just wondering if this is proven through experiment or ...

Eutectic plot - freezing point lowering

I have a doubt about the correlation between eutectic plots and freezing point lowering. The freezing point lowering, as well as all colligative properties, is defined in the presence of a volatile ...

Doesn't the eutectic diagram violate Gibbs's phase rule?

EDIT: As the question hasn't attracted any answers, I tried to put in more detail. Gibbs's phase rule for a 2 component system at constant pressure says that $F=3-P$, i.e., that the number of degrees ...

Low temperature sodium salt eutectic [duplicate]

I have a need for a sodium salt that melts below 265 degrees celsius, which will be exposed to liquid sodium metal. The anion is not important, only that it has a sodium cation. I have done a lot of ...

Eutectic Phase Diagram of Al-Si Analysis

Hello, How can I know from this phase diagram: 1. The composition of the alloy Al-Si that allows precipitation to occure? 2. The range of temperatures where the Al-Si is soluble? 3. The range of ...

How can I find the eutectic point of gallium and aluminum?

I've been interested in liquid metals for a while, but I've stayed away from mercury for obvious health reasons. I have a sample of gallium and I've seen a liquid metal mixture of gallium and aluminum....

Melting point of ocean salt: eutectic?

I'm interested in the melting point of ocean salt. While sodium chloride has a melting point of 801 °C, ocean salt contains 15 % other ions, mainly sulphate, magnesium, calcium and potassium (the ...

What are the advantages of eutectic solvents over aqueous solutions for electroplating?

I'm trying to electrically strip lead contamination from aluminum. This answer suggests using a deep eutectic solvent (DES) as the conducting liquid for plating the lead onto a copper cathode. But ...

Why did my deep eutectic solvent solidify?

I'm finally getting around to beginning to test this deep eutectic electrolyte. I mixed choline chloride with urea in a 1:2 mole ratio in a glass container. It formed a sludge. I sealed the ...
