4.5: Producing High Temperature Refractories
Refractories are materials needed for handling high temperature
liquids, gases and solids, e.g., for industrial processing.
Applications include solar furnaces, casting molds for molten
materials, heat exchangers, and aerobraking heat shields.

Water could come from the Moon, but really, NEAs are a much
better source, especially for the amounts we need. Maybe there'll
be enough to throw it away in traditional concrete, but probably
not.
