This paper reports on the reaction of zirconia combined with silica and halide mineralizers and then fired in a nitrogen atmosphere. X-ray analysis showed zircon was formed, demonstrating that an oxygen atmosphere is not necessary for the formation of zircon. The reaction mechanism is the same as that forming zircon in air, involving transport of the silica as a volatile halide, followed by diffusion of silica and oxygen across the product layer to a reaction site on the zirconia.
