Zirconium oxide can be produced directly from zircon by thermal decomposition in an electric furnace or a plasma reactor. The product of both processes is dissociated zircon that consists in a mixture of zirconia (ZrO2) and silica (SiO2). The silica is subsequently leached out by boiling caustic soda or sodium hydroxide.
