Abstract: There exist two Pa peaks of vacuum pressure when TiB2 is consolidated by Spark Plasma Sintering. The second Pa peak was investigated in this paper. The results indicate that it is caused by vapor deposition from chemical reaction in sintering. The state of original pow- der and sintering technology have influence on the second Pa peak which also has effect on the microstructure of the sintering materials.

Key words: second Pa peak, chemical reaction, influence
