Nano-size Hydroxyapatite Powders Preparation by Wet-Chemical Precipitation Route
In this study, wet-chemical process was performed to prepare nano-size hydroxyapatite (HA) powders (≈10 nm) by varying concentration (low, medium and high) of the starting solutions in order to increase the amount of as-dried HA powders with different process conditions. Particle sizes and density were analyzed and differential thermal analysis was used to determine the glass transition (Tg) an...
متن کاملThe Effect of Polyvinylpyrrolidone on the Formation of Copper Nanoplates in Wet-Chemical Reduction Method
In this work, we report synthesis and characterization of copper nanoparticles in polymer matrix by wet-chemical reduction method using ascorbic acid as reducing agent, copper (II) sulfate as metal precursor and polyvinylpyrrolidone k-30 (PVP K-30) as surfactant agent. The reaction was carried out in a high-speed stirring mixture at room temperature under nitrogen atmosphere. Characterization o...

متن کاملA novel wet-chemical method for preparation of silver flakes
A novel wet-chemical method for the preparation of silver flakes was studied. The well-defined particles were prepared by directly adding FeSO4 solution into AgNO3 solution containing citric acid at an agitation speed of 150 r/min at room temperature. The products were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The results show that particles are irregular ...
متن کاملChemical Reaction Considered Numerical Simulation on Preparation of AlN Nano Powder by Non-transferred Thermal Plasma
Numerical simulation on the thermal plasma characteristics was carried out inside of the DC non-transferred thermal plasma system to preparation of AlN nano powder. Especially, chemical reactions were considered between thermal plasma, Al metal bulk, and NH3 gas inside of the reactor by FLUENT computational fluid dynamics code. In our simulations, 2-D axis-symmetric domain was assumed, and the ...
