I appreciate the verisimilitude in the descriptions that you added to Factoriopedia. That is what I was going for in my extensions to Nullius.
I can clarify a few things from how I designed it:
The inorganic chelating agent recipe has both sodium metaphosphate and sodium metasilicate. Silica is used for the latter.
Nickel wires, besides being fair conductors, are also heat-tolerant. That is why they are used in electron guns and foundries. The best metals for high-temperature wires are heavy metals that can't be found on Nauvis.
Calcium hexaboride is used in electron guns for its low work function. In real technology, electron guns use lanthanum hexaboride.
Optical glass is low-dispersion fluorophosphate glass.
