One step reduction of Boric Acid to boron carbide nanoparticles
Source abstract
Abstract
Abstract Boron carbide (B 4 C) nanoparticles have been successfully synthesized by carbo-thermic reduction of Boric Acid (H 3 BO 3 ). This method is relatively low temperature synthesis route. It can be used for large scale production of B 4 C. The synthesized nanoparticles have been characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and differential thermal analyzer (DTA) techniques. XRD analysis confirmed the formation of single phase B 4 C. SEM and TEM analysis confirmed that the particles are spherical in shape with an average particle size of 12 nm. DTA analysis shows that the phase is stable upto 900 °C and the material can be used for high temperature applications.
