Physical and Chemical Parameters Controlling the Homogeneity of Fine Grained Powders and Sintering Materials

  • Max Paulus
Part of the Materials Science Research book series (MSR, volume 11)


The necessity of very homogeneous, fine grained powder for controlled grain growth and full density sintering is evaluated on the basis of Kirkendall effect and the local inhibition or acceleration of crystal growth. Furthermore, physical and chemical interactions along the different stages of processing on ceramics may limit the control of composition, homogeneity, porosity and grain size of the final product. After a short review of the numerous methods which have been established in order to improve homogeneity of the powders, the cryogenic method is considered in detail.
