Preparation and Tribological Properties of CaF2 Nanocluster Capped with oleic Acid as Lithium Grease Additive
油酸修饰纳米氟化钙的萃取法制备及其摩擦学性能

An oleic acid surface-modified calcium fluoride(CaF2) nanoparticle(OA-CaF2) with average diameter of 23 nm was chemically synthesized using an extraction method.The morphologies and crystalline structures of the powder have been characterized by transmission electron microscopy(TEM) and X-ray diffraction(XRD),while the chemical composition and further information on the structure of the nanoparticles have been characterized by FT-IR.The results showed that surface of CaF2 nanoparticles had been modified by ...
