Pressing is the dominating shaping technique for ceramics and powder metals. Submicron and/or composite powders require adequate preparation to achieve a pressing performance that ensures dense compaction into a homogeneous state.
Conventional powder granulation methods (spray drying, sieve granulation etc) show drawbacks. Migration phenomena cause inhomogeneities and hard granules that do not disintegrate properly during pressing.
The preparation of a powder suspension by applying colloidal processing combined with sufficient mechanical treatment provides optimal homogeneity
- can be preserved by spray freezing and subsequent freeze drying resulting in
Homogeneous powder granules with superior performance made by Freeze Granulation.
