2019/6/1· Their ceramic yields were 57.7%, 79.1%, 87.4% and 88.1% respectively. As expected, the uncured PCS fiber had the lowest ceramic yield, and well-developed crosslinking structure of the A − PCS f and O − PCS f after dissolving the uncrosslinked core part by THF endowed them with ceramic yields as high as ˜88 wt%.

How to Write the Electron Configuration for Silicon (Si) In order to write the Silicon electron configuration we first need to know the nuer of electrons for the Si atom (there are 14 electrons). When we write the configuration we''ll put all 14 electrons in orbitals around the nucleus of the Silicon atom. In writing the electron configuration for
