The particle size distribution data of ultrafine potassium bicarbonate and ammonium dihydrogen phosphate particles.

In this work, we developed an improved method, namely bubble-assisted freeze-dissolving in antisolvent (B-FDas), which enhances the production of ultrafine particles in two systems: potassium bicarbonate and ammonium dihydrogen phosphate. This improvement is achieved by introducing a continuous stream of bubbles during the freeze-dissolving process. The initial concentration of the particles ranged from 0.02 g/g to 0.10 g/g, and the volume of the frozen ice particles varied from 0.01 to 0.08 cm3. The tables presented herein illustrate the particle size distribution of the two types of particles under different conditions, including comparisons between different methods, the same volume but different concentrations, and the same concentration but different volumes.
