Mechanisms Affecting Dispersion Stability
- this involves polymers added to the system adsorbing onto the particle surface and causing repulsion
- It is a simple process requiring just the addition of a suitable polymer
- However it can be difficult to subsequently flocculate the system if required
- The polymer can be expensive and in some cases undesirable (e.g. when a ceramic slip is cast the polymer has to be burnt out causing shrinkage and possible defects)
