Phosphorus

Phosphorus + carbon = bad

Phosphorus is common in the human body. It links together our DNA and transports all of our energy (ATP). Phosphorus in the human body is usually found surrounded by oxygen forming phosphate [[1]] ions. Phosphorus is capable of forming strong covalent bonds to carbon atoms. Nontheless these bonds usually are not/seldomly implemented within the human body (Just like it is with chlorine). Many of the compounds which contain direct covanent phosphor to carbon bonds are highly to extremely toxic [2]. (TODO: investigate inhowfar they are produced in combustion)

Atomically precise technology products can trap phosphorus

Thus as with chlorine mixing carbon and phosphorus in products of atomically precise technology without enough silicon and metals to make it incombustible and non-outgassing at destructive temperatures might be a bad idea.

Usability of phosphorus in atomically precise manufacturing and technology

• In earlier atomically precise manufacturing appatite (calcium phosphate) may plax an important role since it can be handled in an aqueous environment which is shown by biomineralisation.

A good starting point may be:

• the phosphate minerals: [3]
• the phosphide minerals: [4]
  Fe₃P Ni₃P Rhabdite/Schreibersite endmembers [5]
  Fe₃P Ni₃P Allabogdnite endmembers [6]
• the artificial phosphides [7]
  BP [8]
  TiP [9]
  Zn₃P₂ [10] (highly toxic - stay away)
• the artificial phosphates [11]
• other phosphor compounds [12]
