This channel aims to help you to understand solids. Solids are all around us and are largely the focus of the field of study known as materials science. By understanding the way solids are put together (their microstructure) we can understand why various materials behave as they do. In many cases we can even use our understanding of solids to change the way they behave.

    Hi Scott. GREAT description, Thanks! If the Cation can be about 23% of the Anion, we're describing its maximum size that can occupy the interstitial.... (FYI: description above reads "minimum").

  • @ScottRamsay
    @ScottRamsayАй бұрын

    Thanks for your kind words! The cation can be larger than the size where it just touches its nearest neighbor anions. If it’s smaller, then it would occupy the next smaller interstitial site. The maximum size for the tetrahedral site corresponds to the minimum size for the octahedral site.

    Thank you, that was helpful. I know you touched on it at the end, but just to confirm. So the parallel planes (the other three sides of the cube), they aren't required because they are just 'translations' of the planes you did shade in?

    Awesome video, but there is something confusing me , for C alpha and C liquid how they can be used as percentages of solid component or liquid component, as i understand the definition of C alpha or C liquid as they are compositions ratios in which at a particular temperature they are at solidus line or liquidus line , so if can any one clarify for me this confusion and thanks

    For aluminum/aluminium, 143 pm is metallic radius (used in video). Other value (in pm) are: 118 (calculated radius), 125 (empirical), 126 (covalent radius in single bond, coordination number =3), 113 (covalent double bond), 111 (covalent triple bond) and 184-225 (various van der Waals radius, depend on method used).

    Can I rotate the coordinate system by 90 degrees in any direction? If my intercepts are correct, I should be fine, right?

  • @ScottRamsay
    @ScottRamsay8 ай бұрын

    If you mean just axes and not the plane also, then no. This would result in a different plane. For example, looking at the front face of a cube along the x-axis, you’d be looking at the (100) plane, but looking at a cube face along the y-axis you’d be looking at the (010) plane. If I rotated the whole thing, axes and planes, 90 degrees about the z-axis then the plane would remain the same but my perspective would have changed.
