| Abstract: |
Particle settling and cake formation can be a serious issue for transport, storage and reliable processing of SPS suspensions. The stability and rheology of Suspensions under transport and storage conditions have been investigated. The discussion addresses colloidal stabilization and network structure formation as driving factors for rheological engineering of SPS suspensions. Using these findings we present a supply model that poses minimum risk for reliable SPS processing.
Extremely promising Coating properties have been demonstrated.
