Synthesis and characterization of high-purity micro-spherical (NH 4 ) 2 RuCl 6 particles using chemical separation combined with spray dried techniques

Synthesis and Characterization of Nanoscale Tungsten Particles with Hollow Superstructure Using Spray Drying Combined with Calcination Process

“…Spray drying technique is developed to be a clean, rapid, reproducible, low-cost, and easily scaled-up method to produce spherical nanoscale particles due to instantaneous transition between liquid (solvent) and solid (solute) phases [16–22]. Spray drying method compared with other drying techniques is widely used in industrial milling [16, 20].…”

“…During the process of spray drying, the solution (solute-solvent) is completely atomized and dispersed into chamber (hot gas) when interacted with the high-pressure gas at the nozzle. Afterward, fogdrops atomized are evaporated in the drying chamber and spherical or near-spherical solid particles are formed simultaneously [17, 22]. The particles prepared by spray drying have high dispersibility, good sphericity, and homogeneity.…”

Synthesis and Characterization of High-Purity Ultrafine Platinum Particles by Chemical Refining Method

“…Spray-drying is a known method for producing spherical particles due to the instantaneous transition from the liquid (solvent) to the solid (solute) phase [13][14][15][16][17][18][19]. Compared with other drying technologies, spray-drying is clean, rapid, reproducible, inexpensive, and easily scaled up, which is why it is widely used in industrial milling [14,17,18].…”

“…Afterward, the atomized fogdrops evaporate in the drying chamber and form spherical or near-spherical solid particles simultaneously. The powder prepared by spray-drying has high dispersibility and good sphericity and homogeneity [13,18,19]. Moreover, it is of high purity since no impurity is introduced during the spray-drying stage.…”

“…Moreover, it is of high purity since no impurity is introduced during the spray-drying stage. The particle size distribution ranging from 0.5 to 5 μm can be obtained by controlling spray-drying parameters, because the result is heavily affected by the parameters [19]. Therefore, spray-drying is an effective way to prepare a high-purity ultrafine powder [18,19].…”
