| 當(dāng)玻璃中PbO引入后,Pb2+電子層最外層兩個(gè)未配對(duì)的6S電子,這兩個(gè)未配對(duì)電子存在,使Pb2+離子極化率極高而且易被O2-極化,極化導(dǎo)致離子變形和離子間距縮短,從而不僅部分使Pb-O間距進(jìn)一步縮短,而且場(chǎng)強(qiáng)增大,對(duì)O2-吸引力增強(qiáng),使Al-O與Si-O鍵力減弱。 |
木蟲 (小有名氣)
| After adding PbO to glass, due to the existence of two unpaired electrons in the outermost shell of the Pb2+ electron layer, the Pb2+ ion becomes polarized and absorbs the O2- anion easily. Such polarization causes changes in the ions, shortening distances between ions, thus resulting not only in closing the distance between Pb and O ions, but also increases the force field. This in turn causes O2- to increase attraction such that the bonds between Al and O, as well as Si and O to be weakened. |
