Synthesis of wollastonite nanowires via hydrothermal microemulsion methods

Abstract The monodispersed wollastonite nanowires with diameter of 20∼30 nm and up to tens of micrometers in length were prepared via hydrothermal microemulsion method, and the products were characterized by XRD and FETEM. Tobermorite nanowires were first obtained after hydrothermal treatment, and after calcination at 800 °C for 2 h, tobermorite nanowires transformed to wollastonite nanowires and the wire-like structure was preserved.
