Please let me know, if vigorous stirring increases homogeneity and thereby likelihood of getting a novel crystal? Or should I choose slow stirring? Please let me know the pros and cons.
It always depends on system but in most cases the vigorous stirring increase the surface area of reacting particle, homogeneity increases and help in reaction. however, for synthesis of new crystals. several parameters should be keep in mind such molar ratio, time, temperature, use of mineralizers etc.
