Nogita et al. [13] reported that the primary Si nucleation temperature is greatly depressed (about 40 C) by the addition of Sr, resulting in a higher growth rate after nucleation. As a result, Si crystals become less faceted and more dendritic with the increase in Sr additions. crew resource management instructor https://mcneilllehman.com
