Characterization and Exploration of Placket–Burman-Designed Porous Calcium Carbonate (Vaterite) Microparticles
The objective of the research was to identify significant variables that impact the porosity-related properties of CaCO3 particles. The Placket–Burman design was employed to screen multiple variables, including pH, molar concentrations of calcium chloride and sodium carbonate, temperature, concentration of Gelucire 44/14, Cremophor RH40, Solutol…
