Preparation and Characterization of Magnesium Borate Whisker

Article Preview

Abstract:

Being a new whisker products with high performance to price ratio, magnesium borate whiskers with a length of 10 - 50μm and a diameter of 0.5 - 2μm were prepared by molten salt and characterized by XRD, FT - IR, SEM and chemical titration. The experiments show that the synthesis conditions are as follows: raw materials ratio: Mg:B:flux =1:11.05:1-3.5(mol); reaction temperature: 800 - 950°C;reaction time:6 - 10hours; flux: NaCl、KCl or NaOH.
