Controllable preparation of inorganic nanomaterials with specific morphology and structure is very important for their applications in various fields. Herein, a general strategy was proposed to controllably synthesize nano-CaCO3 via water-in-oil microemulsion method the rotating packed bed reactor. By tuning key parameters, four primarily analyzed morphologies, including spherical, spindle-like, clustered, or linear formations, can be selectively obtained. The diameters nanospheres are adjustable within range 4-20 nm, lengths nanowires tuned from 100 800 nm. Notably, crystal forms, amorphous, vaterite, aragonite, calcite, also synthesized. Importantly, these prepared have excellent dispersity, which well-dispersed dozens types liquid media form transparent semitransparent nanodispersions. This work provides producing nanomaterials, enabling precise control over desired ensuring commendable dispersibility, greatly foster broader preparations
