Metal free gemstone-like compounds are [[gemstone like compound]]s compounds that:
+
* [[Metal free gemstone-like compounds]]
* do not contain metal atomns
+
* do not neccesaruily need to but may include carbon
+
Or redundantly:
+
* [[organic gemstone-like compound]]s with the condition on needing to contain carbon dropped.
+
 
+
This gives a slightly bigger subclass of [[gemstone like compound]]s.
+
 
+
Metal free gemstone-like compounds include:
+
* All [[Organic gemstone-like compound]]s
+
* BN [[Boron nitride]] – likely incombustible
+
* BP [[Boron phosphide]] – incombustible
+

=== Adding sulfur – This time it works – somewhat ===
+
 
+
Unlike with [[Organic gemstone-like compound]]s
+
in the case of the ones without a lot of carbon and nitrogen adding sulfur to the mix this time works (well somewhat)
+
Compounds do not become high explosives that yearn to become gasses or liquids.
+
 
+
Adding a sulfur into the mix in high ratio does not make the metal and carbon free gemstones unstable (decomposing to gasses) immediately <br>
+
but does instead lead some [[oddball compound|quite exotic stuff]] crossing over to polymeric nature:''' <br>

This article defines a novel term (that is hopefully sensibly chosen). The term is introduced to make a concept more concrete and understand its interrelationship with other topics related to atomically precise manufacturing. For details go to the page: Neologism.


Organic gemstones shall include all gemstones that ...

  • ... do not contain metals but only light non-metallic elements
  • ... do contain carbon

Typically These ...

  • ... contain volatile elements (carbon, nitrogen)
  • ... are combustible.
  • ... become unstable if too much oxygen (or sulfur) is mechanosynthetically added

List of organic gemstone compounds (attempting exhaustiveness)

The options are rather limited so it seems here (for once) one quickly can arrive at a quite exhaustive list of the most basic possible structures.
As always on this wiki: The heavier more scarce elements (Arsenic, Selenium, ...) are excluded for materials for eventual large scale structural use.

Why adding oxygen or sulfur only works for trace amounts

  • Adding oxygen in high quanity leads to carbon dioxide CO2 which is (as one should now) not stable as a covalently cross-linked solid
  • Adding sulfur in huge quantity leads to carbon disulfide CS2 wich is an (interesting) liquid in its thermodynamic stable form
  • Nitrogen just wants to mind it's own business and wants to get back to its molecular di-nitrogen from with its strong tripple bond (usually a quite exoergic reaction)

Metastable solid state forms (not referring to being frozen) may be possible (especially at low temperatures) but activation energies are low making these compounds into dangerous high energy explosives.
