Study on Test Method for Strength of Ceramic Spray Dried Powder
We have studied the test method for strength of spray dried ceramic powder using manual press and UTM. which is one of the important to influence forming process. We could observe the compaction behavior using manual press. However the measurement of granule strength was only possible with UTM capable of providing the condition of a constant pressing rate. The strength of granule can be measured from the slope change of compaction curve and agrees with the value which is obtained from the combination of saturated tap density and compaction curve. So we proposed the accurate method to measure the strength of granule from the results of this study.
Key words: Spray dried powder, Strength, Tap density, Compaction, Springback effect
