Results of TMA and Colors of the Sintered Samples after Measuring
The conditions for TMA were compaction pressure : 250MPa, pellet diameter : 10mm, thickness : about 3mm, heating rate : 10°C/min, loading : 10g.
W10 : Contents of particles larger than 10µm, SM : Maximum shrinkage, T0 : Temperature at the maximum shrinkage, T5 : Temperature at the expansion coefficient becomes 0.0005/°C, TS5 : Temperature rectified using the correlative equation, TSK : Nominal temperature equivalent to its SK.
