For a paper on the "hardness" of Rhenium Diborane, and yes it will
Whenever topic of scratching diamonds comes up, it is always grabs
my attention. There are a few problems with this discussion.
Rhenium diboride simply means rhenium and two atoms of Bohr, is salt
and not metal. Rhenium diboride relates to rhenium in the same way as
aluminum relates to sapphire. Sapphire can be called aluminum oxide.
If I want to be real fancy, I can even call it diAluminum triOxide,
which means two atoms of aluminum combined with three atoms of
Second thing is that scratching the diamond. I question it because
according to document, the test was done on diamond film and not on
crystal. In diamond films C-axis orientation coincides with film
Z-direction, or along film thickness. Running a point across a
diamond film make film very vulnerable to cleavage. That is exactly
why we do not use scratch test in gemological examinations anymore.
is a known fact that diamond can be damages by contact with softer
than diamond substances.
Until more reliable tests are done, I shall remain highly skeptical
of any claims of similar nature.
