Boron

IBoron ibonakaliswe kwitheyibhile yeperiodic kunye nesimboli B, inombolo yeathomu yesi-5, kunye nobunzima beathom obuyi-10.81. I-Elemental boron, eneempawu ze-semi-metallic kunye ne-semi-conductive, iqulethwe kwiqela le-3A kwitheyibhile yeperiodic. I-Boron ikhona kwindalo njenge-isotopes ezimbini-i-B10 kunye ne-B11. Ngokuqhelekileyo, i-borates ifumaneka kwindalo njenge-B10, isotope 19.1-20.3% yexesha kunye ne-B11 isotope 79-80.9% yexesha.

I-boron ye-Elemental, engafumanekiyo kwindalo, yenza iibhondi kunye nezinto ezahlukeneyo zetsimbi kunye nezingezo zetsimbi ukuvelisa iikhompawundi ezineempawu ezahlukeneyo. Ngoko ke, iikhompawundi zeborate zingasetyenziswa kumashishini amaninzi ahlukeneyo ngokuxhomekeke kwiikhemikhali ezibophelelayo ezahlukeneyo. Ngokwesiqhelo, iikhompawundi ze-boron ziziphatha njengeekhompawundi ezingezizo ezentsimbi, kodwa i-boron esulungekileyo inokuhanjiswa kombane. I-crystallized boron iyafana ngenkangeleko, ineepropathi zokubona, kwaye iphantse yaqina njengedayimani. I-boron ecocekileyo yafunyanwa okokuqala kwi-1808 yi-chemist yaseFransi u-JL Gay - uLussac kunye no-Baron LJ Thenard kunye ne-English chemist H. Davy.

Iithagethi zilungiswa ngokuxinzelelwa kwe-Boron powders kubuninzi obupheleleyo. Iimathiriyeli ezidityanisiweyo zikhethwa ngokuzithandela kwaye zenziwe ngendlela efunwayo.

Izixhobo eziTyebileyo eziZodwa nguMvelisi weThagethi yokuSputtering kwaye inokuvelisa ubunyulu obuphezulu beBoron Materials Sputtering ngokwemigaqo yabaThengi. Ukuze ufumane inkcazelo engakumbi, nceda uqhagamshelane nathi.
