Studies of the Surface of SiC Nanometer Powder

Abstract

Abstract: The surface composition and bonding of a wide variety of SC nanometer powders were characterized by TEM, IR and XPS. The results show that oxygen mainly
exists in the form of physical adsorption for fresh SiC nanometer powder(adsorbed oxygen---78.25%, combined oxygen---21.75%). When the powder was kept in air for
a month, its O/Si mole ratio added from 0.49 to 0.70, when the powder was kept in air for two month, the O/Si mole ratio added to 0.77. The results show that the
oxidization of the powder becomes slower after a month. Oxidization of the powder is easier in wet air than in dry air. Oxygen content decreases with increasing Ar⁺
sputtering time, and oxygen is mainly distributed over the surface of the powder.

Key words: SiC nanometer powder, surface oxidization, adsorbed oxygen, combined oxygen
