"Silicate Magic" certainly fits in there.
I used to use transmutation doped silicon.
Transmutation, there’s the goal of alchemists turned into an industrial process...
Not major just solid chemistry and materials science. Silicate is just silicon oxides. Otherwise know as sand in it’s SiO4 form. Silica is available in unlimited amounts....
“The mass of Earth’s crust is 59 percent silica, the main constituent of more than 95 percent of the known rocks.”
Silica based anodes are already in a number of commercial batteries with more on the way. Silica has triple the capacity vs carbon with lattice structure for lithium,sodium, calcium and magnesium , Iron is also being looked at since it’s 2+/3+ in electron shells.
