Fabrication of ZrC-SiC Powders by means of Liquid Precursor Conversion Method Using ZrC Precursor and Polycarbosilane

摘要：

　　ZrC-SiC powders were fabricated by means of liquid precursor conversion method,using Zr containing polymer precursor and polycarbosilane.The effects of staring reagents and the pyrolysis temperature on the fabrication of ZrC-SiC powders were studied.Results show that ZrC-SiC powders with different ZrC/SiC ratio could be formed when the staring reagents were different.Pyrolysis temperature affects the pyrolysed product.When temperature was lower,less amount of ZrC was formed in the powder.The size of crystallite and morphology of the synthesized powders were characterized by transmission electron microscopy and scanning electron microscopy.
