AGGLOMERATION ASSESMENT OF NANO-SIZED ALUMINA POWDERS
Abstract: Nanoparticles exhibit a high reactivity and strong tendency towards agglomeration. In this study, aluminum oxide (alumina) nanoparticles were characterized by gas adsorption (BET), transmition electron microscopy (TEM) and photon correlation spectroscopy (PCS) techniques to assess the agglomeration of the particles. There is a good correlation between the BET and TEM measurements b...
متن کاملThermal Plasma Synthesis of Nano-sized Powders
Thermal plasmas, normally generated by DC (direct current) arc or inductively coupled RF (Radio Frequency) discharge, can be described as a high enthalpy flame with extremely high temperature fields (1,000~20,000 K) and a wide range of velocity fields from several m/s [1-5] to supersonic values [6-7]. Since the resultant huge enthalpy can be realized for various kinds of plasma forming gases an...
متن کاملStructural characterization of nano-sized calcium deficient apatite powders.
Nano-sized calcium-deficient apatitic (CDHA) crystals with Ca/P ratios from 1.5 to 1.67 were synthesized using wet chemical method and of needle-like shape with 5-10 nm in diameter and 40-50 nm in length was observed. The structural environment of the Ca atoms in all the CDHA nano-crystals has been investigated using EXAFS, XANES and EELS. The results reveal that a maximum Fourier transform amp...
