Rheology & Suspensions

Fine Powders & Suspensions

Inorganic powder suspensions are encountered during the fabrication of many products. Often suspensions represent the starting point in the manufacturing process.

Therefore, understanding and controlling the behaviour of a suspension avoids problems at subsequent processing stages.

Benefits that can be expected from full understanding of your suspensions are:

• Higher yields
• Improved end-product performance
• Reduced waste creation
• Faster process routes
• Fast introduction of new products

CERAM invested heavily in the following analytical equipment for characterising high solids content suspensions typically encountered on factory:

Once a suspension is fully characterised, changes are often needed to achieve optimised performance for subsequent processing. CERAM can assist in two generic ways:

Expertise in ceramic factory processing enables CERAM to assist on a variety of issues.

These Include

• Batch to batch dispersion uniformity
• Aggregation and ageing problems
• Appraisal of new surfactants/additives
• Tailoring suspensions to balance processing issues (eg casting rate)
• End product performance.

Typical application industries include

• Telecommunications
• Electronic components
• Biomedical
• Clay/other mineral suppliers
• Refractories.
