The first link 404'd but then there is this:

Lubrication potential of boron compounds: An overview
R. B. Choudhary, P. P. Pande
First published: 07 March 2006 Citations: 34

Since I don't care as much as all y'all, I didn't get any further than the Abstract


But wait! First link under images:
www.slideshare.net/slideshow: Manufacture and characterization of Boron Oxide solid lubricant

For the visually stimulated:


www.slideserve.com:
The Functional Attributes and Utilization of Borates in Lubrication Nanotechnology

Now this has my attention. Can you see why I'm fascinated by this figure? It's not the rare Snub Truncated Octahedron because it has seven-sided openings:

I can find all that and I don't even know what a pin test is.

Thx freebeard

The complete 1st paper is here:

This, to me, looks to be a rabbit hole that will take some time...

As for your second link:
Yes I see why you like it from the pics! but not looked further yet.
