JB,
I have been following along here, and think that Borax would be a good 5 hydrate to add to the 2 other hydrates
NH4Al(SO4)2·12H2O Alum
Na2SiO2(OH)2·4H2O Sodium silicate
you said to add a 5 or 9 hydrate to the 2 above hydrates
Na2[B4O5(OH)4]·8H2O borax, this would be a octahydrate in a fully hydrated form. § Borax pentahydrate (Na2B4O7·5H2O) is a 5 hydrate, a partly dehydrated form, that is commonly sold as detergent ie: 20 Mule Team
borax, is Sodium, Boron oxide, hydrate
mixing correct proportions of these 3 would create a Synthetic Zeolite, and adding just enough SO4 to make the PH neutral at 7, so it acts like the switch you mentioned once it crystallizes
Boron is a P Dopant, and will form up with the Aluminum / Sodium Silicate as part of the structure of the crystal cage that holds the SO4 locked up, and that cage space should hold more SO4 than Alum / Sodium Silicate alone. I think that this combination will create a cage space that is a dodecahedron (12 Faces shape)
Would adding the boron P dopant, make the cell act like a PN junction...?
I do not quite understand where the Ammonium - (Nitrogen / Hydrogen) fits in the crystal though........
