Is there a chart anywhere which lists which oxides are optically transparent and which are colored?

19 December 2019 0 8K Report

Curious to know which metal oxides have color and which don't. For example, a few metal monoxides have a dark or black color (FeO, CuO). Cr2O3 has a greenish color. And so forth.

Are there any ceramics or alloys which have a crystal structure that resembles an octet truss?

I've read somewhere that the octet truss is among the most structurally-stable, weight-bearing structures. I was interested to know if there are any ceramics or alloys which adopt said structure.

In metal diborides (like AlB2, MgB2, TiB2), how many electrons per metal atom does boron need to form the layered hexagonal sheets?

The strangeness of boron as an element is that it generally behaves differently than other members of its family. Instead of acting like a metal typical of group 13, it forms structures that are...
