Ceramic Processing Green Body Formation

General requirements for green body formation
Homogeneous packing of particles Severe variation in powder packing will lead to heterogeneity in final product microstructure and, in most cases, inferior properties (mechanical or thermal)
High packing density of particles Higher powder packing density leads to higher density after sintering
Special scenarios
Introducing heterogeneity
−Example: functional graded coating or electrodes
Reducing packing density
−Example: high porosity wanted for electrodes for fuel cells
