Preparation of Spherical Ultrafine Silver Particles Using Y-Type Microjet Reactor

Abstract

Herein, micron-sized silver particles were prepared using the chemical reduction method by employing a Y-type microjet reactor, silver nitrate as the precursor, ascorbic acid as the reducing agent, and gelatin as the dispersion at room temperature (23 °C ± 2°C). Using a microjet reactor, the two reaction solutions collide and combine outside the reactor, thereby avoiding microchannel obstruction issues and facilitating a quicker and more convenient synthesis process. This study examined the effect of the jet flow rate and dispersion addition on the morphology and size of silver powder particles. Based on the results of this study, spherical and dendritic silver particles with a rough surface can be prepared by adjusting the flow rate of the reaction solution and gelatin concentration. The microjet flow rate of 75 mL/min and the injected gelatin amount of 1% of the silver nitrate mass produced spherical ultrafine silver particles with a size of 4.84 μm and a tap density of 5.22 g/cm3.

Y-tube assisted coprecipitation synthesis of iron-based Prussian blue analogues cathode materials for sodium-ion batteries

“…As a method conducive to continuous production, it not only ensures the quality and stability of batch products but also offers advantages in terms of low cost and simplicity in synthesis. [54][55][56] The key to synthesizing high-performance PBAs lies in controlling the reaction process and minimizing oxidation as much as possible. Therefore, theoretically, the Y-tube is suitable for the production of PBAs.…”

“…Regarding the preparation of advanced materials, the following articles are included in this Special Issue. Wang et al prepared micron-sized silver particles using the chemical reduction method by employing a Y-type microjet reactor, silver nitrate as the precursor, ascorbic acid as the reducing agent, and gelatin as the dispersion at room temperature [7]. Using a microjet reactor, the two reaction solutions collide and combine outside the reactor, thereby avoiding microchannel obstruction issues and facilitating a quicker and more convenient synthesis process.…”
