One could assume Sorium is a gas based on it being the only mineral available on gas giants.
and makes me a sad Auroreer that my geological survey teams can not improve the quantity and accessibility of for that reason.
I don't have Aurora in from of me but:
Duranium
Neutronium
Corbomite
Tritanium
Boronide
Mercassium
Sorium
Uridium
Corundium
Gallicite
I always assumed Duranium was just a metal alloy. Similar to steel, titanium or aluminum. This is why everything requires it.
Sorium was a fuel for ships and I don't think used anywhere else. Maybe not the go boom kind like a petroleum product, but more like a radioactive element used to fuel nuclear reactions. In that regards it is unique that it is stored in liters. I suppose you could RP that it was liquified in refinement to make it easier to handle.
Corundium is used in mine and auto mines, is it used for anything else? My thought was that the drill heads for the mines use it. For that reason the initial mineral requirement should have been less to build the mine and it should have been a consumable which required regular deliveries of the material to keep mining operations running. But oh well.
The rest I don't recall off the top of my head.
Gallicite is primarily used for shipyard construction, yes? To me that makes me think that most of the newtonian elements are toxic or dangerous for human or conventional materials to handle in a raw state and that the gallicite is used as a shielding agent in manufacturing equipment until the completed product is done being manufactured.
