Abstract:

Development work has shown that powder varies throughout a large calcination bed. The tops are more sinterable and have a finer particle size distribution than do the bottoms. It was shown that a very uniform powder was obtained from batch to batch in large calcination beds when the total powder from each run was blended to obtain a composite powder for each run. Precompaction was evaluated as a method to increase powder bulk density for better fill and flow properties. The precompacted powder was far superior to the normal powder with respect to these characteristics. However, some preliminary data indicate that the dielectric strength of parts prepared from powder previously precompacted at high pressure 18,000 psi may be adversely effected. Extrusion development has shown that water soluble starches can replace floc-gel starch as a binder. Some control problems have been evaluated. Author
