octaédrico
- But when you tilt the octahedral, you introduce flexibility.
- octahedral aluminum
- octahedral coordination
- octahedral sites
Examples
-
In this study, both fly ashes had approximately 40 to 45% of aluminum in octahedral coordination, with similar quantities converted to tetrahedral coordination during geopolymerization (25 to 30%) (Table 4).
Academic text (2017) -
Yeah, based on a on an octahedral geometry.
-
And you can set up and make an octahedral geometry here.
-
Therefore, there is no orbital degeneracy and no deformation of the octahedral cell.
Academic text (2004) -
Two of them, N = 24 and N = 48, have octahedral symmetry; N = 44 has cubic symmetry; and N = 72 can adopt several symmetries, including icosahedral.
Academic text (2004) -
It also facilitates the incorporation of the aluminum in the matrix with a relatively uniform and stable conversion of more octahedral aluminum units into the tetrahedral form.
Academic text (2017) -
A high quantity of aluminum present in octahedral coordination in the precursor fly ash, and conversion of this into tetrahedral units during alkali dissolution, is required to obtain high compressive strength.
Academic text (2017) -
Generally, one of the simple ways in which compression can be achieved is by increasing the local coordination number—for example, by progressing from tetrahedral to octahedral coordination of silicon by oxygen in silicates.
Academic text (1998) -
The mineral displayed a beautiful, shiny octahedral form that glimmered in the light.
-
In geometry class, we learned how to construct an octahedral model using straws and connectors.

Morphology
octahedral = octahedron (transparent) = octahedron + al
The adjective is formed regularly from the noun 'octahedron' with the common suffix '-al', so its meaning is directly recoverable from the base word.
Etymology
Octahedral comes from the Greek parts octa- meaning 'eight' and -hedron meaning 'face' or 'side', the same 'octa' you see in octagon and octopus because both have eight parts. So an octahedral shape has eight faces, and that is why the word is used for shapes, crystals, and molecules.
