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]

Phosphate gems

  • Rockbridgeite (iron hydroxy phosphate) – Mohs 4.5 – orthorhombic – [13]
  • Crandallite (calcium aluminum water phosphate – Mohs 4 – trigonal – [14]
  • Althausite (magnesium phosphase) – Mohs ? – orthorhombic – [15]
  • Abuite (calcium aluminum fluoro phosphate) – Mohs ? – orthorhombic – [16]
  • Merrillite (calcium sodium magnesium phosphate) – Mohs ? – trigonal – [17]
  • Xenophyllite (sodium iron phosphate) – Mohs ? – triclinic – [18]

With not so common elements

With manganese:

  • Natrophilite (NaMnPO4) – Mohs 4.5-5.0 – orthorhombic – [19]
  • Eosphorite (manganese aluminum water phosphate) – Mohs 5 – orthorhombic – [20]
  • Childrenite (Fe,Mn,Al,water huge cell) – Mohs 5 – orthorhombic – [21]
  • Bobfergusonite (Na,Mn,Fe,Al huge cell) – Mohs 4 (bad) – monoclinic (bad) – [22]

Other elements:

  • Amblygonite (lithium sodium aluminum phosphate) – Mohs 5.5-6.0 (good) – triclinic – [23]
  • Beryllonite (NaBePO4) – Mohs 5.5-6.0 (good) – monoclinic (bad) – [24]
  • Monazite (cerium phosphate) – Mohs 5.0-5.5 – monoclinic (bad) – [25]
  • Xenotime (YPO4) – Mohs 4.5 – tetragonal – [26]
  • Alforsite (barium clorine phosphate) – Mohs 5 – hexagonal – [27]
  • Kosnarite (potassium zirconium phosphate) – Mohs 4.5 – trigonal hexagonal [28]
  • Faustite (zinc aluminum water phosphate) – Mohs 4.5-5.5 – triclinic – [29]
  • Zinclipscombite (zinc iron hydroxy phosphate) – Mohs 5 – tetragonal – [30]
  • Ximengite (BiPO4) – Mohs 4.5 (astounding) – trigonal – [31]
  • Cornetite (copper phosphate) – Mohs 4.5 – orthorhombic – [32]

Not ideal for one or more reasons:

  • Brazilianite (sodium aluminum hydroxy phosphate) – Mohs 5.5 – monoclinic – [33]
  • Brianite (sodium calcium magnesium phosphate) – Mohs 4-5– monoclinic – [34]
  • Aheylite (iron zinc alumimum phosphate with a lot of OH) – Mohs 5.0-5.5 – triclinic (meh) – [35]
  • Augelite (aluminum hydroxy phosphate) – Mohs 4.0-4.5 – monoclinic (bad) – [36]
  • Kovdorskite (magnesium water phosphate) – Mohs 4 (meh) – Monoclinic (bad) – [37]
  • Kolbeckite (scandium water phosphate) – Mohs ? – monoclinic (bad) [38]
  • Cattiite (magnesium 22!!water phosphate) – Mohs 2 (suberbad) – triclinic [39]

Misc notes

Phosphates form a weird middle ground between the

  • incombustible lithospheric world (stones) and the
  • combustible biospheric world (biomass)
