摘要

Abstract

ZrO 2(Y 2O 3) powder and SiC nanopowder were prepared by carbothermal reduction of ZrSiO 4. With the existence of additive Y 2O 3 and other impurities

ZrSiO 4 was dissociated into ZrO 2 and SiO 2 in the condition of 1450—1550?℃. ZrO 2(Y 2O 3)powder was thus obtained via the removal of SiO 2 as silicon oxide (SiO) gas during carbothermal reduction process. SiC nanopowder and small amount of SiC whisker were synthesized form the gas-phase reaction between SiO vapor and supplied CH 4 gas.
