Ceramic properties

What is the composition of the Form labs Ceramic resin? i.e is it silicon oxycarbide (SiOC), silicon carbide (SiC), silicon nitride (Si3N4), silicon oxynitride (SiON), silicon carbonitride (SiCN), silicon boronitride (SiBN), silicon boron carbonitride (SiBCN).

I have an application which currently uses a nickel based alloy that , i am thinking of using a ceramic part instead.

Is there an ideal inert atmosphere to fire the green part in? e.g Argon, Nitrogen, etc…
