This paper deals with the disaggregation and dispersion of ultrafine diamond (UFD) inaqueous medium and utility of UFD in electroless Ni-P composite deposit.

Preparation and agglomeration control of zirconia nano-powder by alcohol-aqueous co-precipitation method;

Application of anti-static agents to eliminate ACF flock agglomeration;

Agglomeration Problems and Anti-agglomeration Measures for the Preparation of Metal Oxide Nanoparticles;

Parameter optimization of aggregate desulphurization process for high sulphur coal;

Due to the great specific surface and surface energy, there are special domino effects that the powders are very easy to aggregate.

Therefore hard aggregate was retarded in α phase transformation process.

The forming mechanism and the control of agglomerate are also concisely discussed.

A technique of preparing nano Al 2O 3 powder by wet chemical method in supersonic field was studied, the effects of supersonic radiation on the formation and reunite of the grains were discussed, and the influence of different supersonic frequency on the agglomerate of the powder was researched.

The results showed that ultrasonic energy can speed up the nucleation of the precursor, ultrasonic dispersion can control the growth and agglomerate of the crystal nucleus, ultrasonic vibration can also affect the process of the transformation into gel during the process of aging, and was easy .
