Effects of ultrafine grinding time on the functional and ...
As shown in Fig. 1 A, the peak 1of SPI powders at grinding time 2, 4, 6 and 8 h had a single and narrow distribution compared to that of grinding time 0 h. Moreover, with superfine grinding time extentding, PSD from SPI powders became more and more narrow. Fig. 1 B shows the average particle size of SPI powders. As presented in Fig. 1B, the average particle size depended on the …
