摘要/Abstract

摘要： 通过电解熔盐KF·ZHF制取氟气，再将氟气与石墨在500℃时进行反应，从而制备了氟化石墨新材料．其密度值为2．53g／cm³、电阻率为3.1×10³Ω·cm，颜色为灰白色，在波数1219、1350cm^－1附近有F-C共价键红外光谱吸收峰．对氟化石墨、石墨、二硫化钼进行摩擦因数测试，结果表明：氟化石墨摩擦因数最小．还讨论了氟化石墨的一些特殊性能和工艺条件．

关键词: 氟气制备, 氟化石墨, 摩擦性能

Abstract: Fluorine gas was produced with the electrolysis of the molten salt KF·2HF, then graphite fluoride was prepared
through the reaction between graphite powder and fluorine gas at 500℃. The real density of the graphite fluoride was 2.53g/cm^3, its electrical resistivity 3.1×10³Ω·cm
and its colour greyish white. The graphite fluoride synthesized had a absorption peak of infrared reflection spectra on F--C covalent bond at approximation wavenumber
1219cm^-1 and 1350cm^-1. By testing friction factor for the graphite fluoride, graphite powder and molybdenum disulphide, the experimental results showed that the friction
factor of the graphite fluoride was the smollest. Furthermore, technological conditions and special properties of the graphite fluoride were dissussed.

Key words: preparation of fluorine gas, graphite fluoride, friction properties
