Pyrophyllite prep?
Looking to prepare specifically pyrophyllite (Al2Si4O10(OH)2), an aluminum silicate hydroxide, while avoiding analogues like kyanite (Al2SiO5,
(Al2O3·SiO2)), kaolinite (Al2Si2O5(OH)4, (Al2O3·2SiO2·2H2O)), mullite (Al6Si2O13, (3Al2O3·2SiO2)). Not finding much in the literature,
unfortunately...
If this works, I'd be reviving a procedure from 1957-ish to grow macroscale tourmaline crystals. Might write a paper on it? Not sure.
