Sedimentation fabrication method

The second method shown uses a weir to control the gasoil interface level at a constant position. This results in better oil/water separation as ail the oil must rise to the height of the oil weir before exiting the vessel. Disadvantages arc that the oil box takes up vessel volume and costs money to fabricate. Sediment and solids can collect in the oil box and be difficult to drain, and a separate low-level shut-down may be required to guard against the oil dump valve failing open.

We studied CdS particles suspended in water. The finest fraction of the powder extracted from the highest layers of the suspension after sedimentation is applied consequently for the fabrication of sintered CdS layers according to the method of Tomsen [8, 9]. The basic idea of the method is the binder material which is used for the recrystallization of the powdered layer of CdS or CdSe at higher temperature. This low-cost technology applicable for solar photovoltaics suffers from a lack of reproducibility owing to the wide range of the dispersivity, which... 

Other processes investigated for planar SOFC fabrication include electrostatic-assisted vapour deposition, vapour phase electrolytic deposition, vacuum evaporation, laser spraying, transfer printing, sedimentation method, and plasma metal organic chemical vapour deposition.
