Synthesis of α-layered sodium disilicate and its tribological properties in liquid paraffin

Author affiliations

Abstract

A high purity α-layered sodium disilicate (α-Na2Si2O5) has been synthesized by employing a mixture of 84% α-Na2Si2O5 and 16% δ-Na2Si2O5 as seed, and characterized by XRD, 29Si MAS NMR, FT-IR, SEM and TG. The experimental data showed that α-layered sodium disilicate may been synthesized by adding 15% seed at 780 °C for 120 minutes. The lubrication of the synthesized sample was investigated. Adding α-Na2Si2O5 in liquid paraffin, the PB value increased by 19.9%. The results indicated that oleic acid may pillar α-layered sodium disilicate. The reaction may increase the separation of layers. An increasing layer distance will be propitious for the glide of silicon layers and improve lubrication ability.
