| Abstract | Desilicated zircona has a great variety of applications. The maximum SiO2 content in desilicated zirconia is <7 mass%. The present techniques to produce zirconia are always accompanied by many drawbacks. So the authors have developed a new plasma process. Desilicated zirconia (88.6 similar to 96.9 mass% ZrO2) and magnesia-stabilized zirconia (> 91.54 mass% ZrO2, < 5.39 mass% MgO) were produced successfully from zircon using a 150 kW plasma rotating furnace. The effects of time and carbon content on the desilication degree were investigated. The mixture treated in the plasma furnace included condensed phases Zr, ZrC, ZrN, ZrO2, C, Si, SiC, SiO2 and gaseous phases SiO, O-2, N-2, CO. The established phase equilibrium diagrams of the Si-C-N-O and Zr-C-N-O systems suggest that the formation Of Si3N4 is thermodynamically impossible, and the formation of ZrC and ZrN is thermodynamically possible in the central high-temperature region of the plasma furnace. Experimental results supported the analyses.; Desilicated zircona has a great variety of applications. The maximum SiO2 content in desilicated zirconia is <7 mass%.
