The dispersion stability of CeO 2 suspensions limits their widespread use in IC manufacturing because unstable slurries can be very damaging to the chemical mechanical polishing (CMP) flattening process. Therefore, this study is based on the use of wet ball milling in synergy with chemical agents to improve the dispersion stability of CeO 2 slurry. . Different organic acids were used as ...

The pump is used to circulate the suspension from the holding tank, through the mill, and back into the holding tank, allowing the production of a fixed batch size, as determined by the capacity of the holding tank [63]. In continuous operations, a receiving tank is also used, allowing the continuous withdrawal of product from the mill.

Summary. A suspension is a heterogeneous mixture of particles of one substance distributed throughout a second phase; the dispersed particles separate from the dispersing phase on standing. In contrast, the particles in a colloid are smaller and do not separate on standing. A colloid can be classified as a sol, a dispersion of solid particles ...

We have developed a simple protocol for the cryopreservation of embryogenic suspension cultures of Cyclamen persicum. Embryogenic suspension cultures in the linear growth phase 710 days after subculture were used for cryopreservation. Of the different cryoprotectants tested during a 2day preculture, M sucrose resulted in the highest regrowth rates of 75%. An additional pretreatment ...

This means that a suspension that is smaller in particle size will be more stable. When particleparticle interaction occurs, it results in floccules or coagulates, increasing sedimentation. By wet milling the final suspension or by dry milling before the suspension, the particles are finely ground. 2. The viscosity of the medium

Colloid mills have various uses in the pharmaceutical industry. The most frequent use of colloid mill is for the comminution of solids and for the preparation of suspensions, particularly suspensions containing solids not wetted by the dispersion medium. It's also used to increase suspension and emulsion stability.
