Green bodies

The second set of synthesis steps shown in Fig. 9.2 concerns the preparation of the green body for the C3 formation. Steps 5-8 are related to generating a flat or curved sheet from the carbon fiber and the precursor of the binder phase. This process can be complicated because the final part made from C3 cannot be changed in its form nor can it be interconnected to another C3 part by reasonably affordable techniques suitable for mass production. The quality of the final product is here decided by the homogeneity of the material distribution and the exact shaping. 

The bromide, [Co(NH3)4Cl2]Br, and the iodide, [Co(NH3)4Cl2]I, of the series are also green bodies, and are formed by the addition of hydrobromic and hydriodic acids respectively to the acid sulphate. 

Crystalline BaTi03prepared by hydrolysis of the alkoxide solutions in the form of dispersion without drying was successfully used to make a ceramic slip formulation, which was then cast as a ceramic green body for microcapacitors 1 to 50 pm thick. 

The development of the microstructure is strongly affected by the perfection of the Si green body. Inhomogeneities in density, pore size and distribution are...
