    Umgubo weBoron

    I-Boron, isiqalelo sekhemikhali esinophawu B kunye nenombolo ye-atom yesi-5, ngumgubo omnyama/omdaka oqinileyo oqinileyo oyiamorphous. Isebenza kakhulu kwaye iyanyibilika kwi-nitric kunye ne-sulfuric acids kodwa ayinyibiliki emanzini, etywaleni nakwi-ether. Inomthamo ophezulu we-neutro wokufunxa.
    I-UrbanMines igxile ekuveliseni i-Boron Powder yococeko oluphezulu kunye nobona bungakanani buncinci bobukhulu beengqolowa. Ubungakanani bethu obuqhelekileyo be-powder particles average kuluhlu lwe-300 mesh, 1 microns kunye ne-50 ~ 80nm. Sinokubonelela ngezinto ezininzi kwi-nanoscale range. Ezinye iimilo ziyafumaneka ngesicelo.
