Hi, You said that low angle boundaries orientation is below 5degree however in the next slides there is an example that shows it as 10 degree in SrTiO3
@peterdavies6179 2 ай бұрын
Yes the 5 degree quote was an approximation, you can go a little higher.

Dear Professor Davies, I am having challenge conducting an isoplethal analysis in CaO-MgO-SiO2 ternary phase system for an overall composition of 49% CaO and 15% MgO. Please can you help on this? Thank you.

How can you tell when a binary reaction is either eutectic or peritectic?
@peterdavies6179 5 ай бұрын
Identify the solid phases and liquid involved; if the liquid composition is in between the solids it is a eutectic; if the liquid is outside both of the solid phases, it is a peritectic. Hope this makes sense.

i should go back and start from the 1st part. I really wished you picked a different composition on the pure MgO field
@peterdavies6179 10 ай бұрын
Thanks for the comment; if you do go back to the earlier videos hopefully you can select a composition near MgO and deduce the path (the primary phase will be MgO). I think you’ll find the paths are more straightforward than the other ones in this video as the only ternary invariant reaction that could be involved is the 1710C ternary eutectic where: L -> MgO + 2MgO.SiO2 + MgO.Al2O3 Let me know if you have any questions
@easyvic1803 8 ай бұрын
Thank you very much for the explanation. The video makes very sense. I am able to understand watching but finding a little difficult reading and working problems. Can you please help me with invariant reaction in 1453,. also finding a composition of 40 Sio2, 15% Al2O3, i know the first solid to crystallize will be fosterite, and the second solid to crystallize is spinel. But i have a question, what will be the composition at when spinel starts to crystallize. and the amount of phase presents. Also what will be the solidification pathway and where the solidification ends, with the 40%Sio2 and 15%Al2O3 .i will be glad if you can help me with this 2 problems.

14:37 , sir can you tell me which compounds are incongruent mealting compound
@peterdavies6179 Жыл бұрын
Sure, A2B and AB2 melt incongruently as they yield a solid and liquid with different compositions when they melt. AB melts congruently and forms eutectics with A2B and AB2 (pure A and our B also melt congruently). Hope this makes sense.

Great video! It helped me a lot in understanding the diagrams. I have a question about solid solubility. At 19:22 from the Si, Mo, Re diagram, can we say that the green point is a solid solution of MoSi2/Mo3Si2/ReSi?
@peterdavies6179 Жыл бұрын
The green point composition is a 3-phase mixture of MoSi2 + Mo3Si2 + ReSi. We would not say it is a "solid solution" of these three as that would imply they are soluble with each other when they are not. So a sample of this composition is inhomogeneous with regions of each of these 3 different phases; if they were soluble (a solid solution) it would be completely homogeneous in composition and structure. The relative amounts of the 3 phases that are present can be calculated from the tie-triangle.

Sir I am from India can I get ceramics body composition
@stefanomaretti3606 Жыл бұрын
Dear prof Davies thank you very much!! Really you have made a great value content in this video series. If i can i'd like ask you a suggestion. I work with traditional ceramics (tiles) where there are 7 main oxides in a tipical composition (Si-Al-Fe-Ca-Mg-K-Na). How can I approach the study of a multi element blend (for example to identify eutectic points)? In your opinion is better consider for example the ternary diagrams Si-Al-K or Si-Al-Ca and consider the sum of the minor oxides (Fe-Ca-Mg-K-Na-K) like K or Ca equivalents? Or it's better try to analyze each binary combination of different minor oxides and after ... lose the mind :)? If you can give me just a hint i'll appreciate it a lot! Thank you again
@peterdavies6179 Жыл бұрын
Thanks for the comment: 7 component systems are tough! Of the 2 approaches you suggest, I think the first is the best first step - i.e. the ternary diagrams Si-Al-K or Si-Al-Ca and consider the sum of the minor oxides. Good luck!
