Induction for thermochemical processes, and associated systems and methods are disclosed. A method in accordance with a particular embodiment includes placing first and second substrates in a reactor, with each substrate having a surface facing toward the other. Method can further include directing a precursor gas into the reactor and activating an induction coil proximate to the facing surfaces of the substrates to dissociate the precursor gas. A constituent of the precursor gas is deposited on both the first and second surfaces, and heat radiated from each surface and/or a constituent deposited on the surface is received at the other surface and/or the constituent deposited on the other surface.
