Boron_R105

UmBohlwa uyinhlwa yevanga enophawu B nenani lobuchwe eliyisi-5. Esimweni sawo esiwumncwebe uyinkimbi eshwabezelayo, emnyama, ecwebezelayo; esimweni sawo sokuswelisimo (amorphous) iyimpuphu ensundu. Njengenhlwa elula kakhulu yeqembu mbohlwa, unezinzuba ezintathu zenhlenge zokukhanda umnanazuba, okukhiqiza imixube eminingi efana nesimunyane sombohlwa, imbiwa sodium borate, kanye nemincwebe eqinile enjenge boron carbide ne -boron nitride.

UmBohlwa uhlanganiswe ngokuphelele yi- cosmic ray spallation kanye neDangazelakazi hhayi nge-stellar nucleosynthesis, ngakho uyingxenye enensada ephansi kunozungezilanga kanye noqweqwe loMhlaba. Wakha cishe amaphesenti angu-0.001 ngesisindo soqweqwe loMhlaba. Igxile eMhlabeni ngokuncibilika emanzini kwemixube yawo evame ukwenzeka ngokwemvelo, izimbiwa e- borate . Lezi zembiwa ngokwezimboni njengama- evaporites, njenge - borax ne- kernite . Amadiphozithi amakhulu kunawo wonke awaziwayo aseTurkey, umkhiqizi omkhulu wamaminerali e-boron.
