Preparation of Monodisperse Colloidal ZnO

Monodisperse colloidal zinc oxide (ZnO) nanospheres with a narrow size distribution were synthesized via a developed two-stage solution method.We controlled the size of the as-synthesized ZnO nanoparticles by varying the amount of ZnO /ethanol suspension added./ethanol suspension added. Get price

Colloidal Processing

Colloidal processing is a wet method for consolidating particles with a high density and homogeneous microstructure by controlling the interparticle interaction in a suspension. Table 4.5.3 shows typical colloidal processing accompanied by a drain step in which the transport media and their driving forces are indicated [65]. Get price
