No more inert atmospheres—Molten salt synthesis prevents oxidation of materials in air

By Lisa McDonald / April 19, 2019

Nonoxide ceramics typically undergo high-temperature synthesis in an inert atmosphere to prevent spontaneous oxidation. Researchers at Forschungszentrum Jülich have now found that potassium bromide keeps nonoxide ceramics from oxidizing when synthesized in normal air.
