I-B4C nanopowder I-Boron carbide powder yezinto zokushisela
Incazelo Yomkhiqizo
I-Micropowder Emnyama B4C I-Boron Carbide Powder Ye-Ceramic Coating
I-Boron carbide, ebizwa ngokuthi idayimane elimnyama, imvamisa iyimpushana enombala.Ingenye yezinto ezintathu eziqine kakhulu ezaziwayo (ezinye ezimbili ziyidayimane ne-cubic boron nitride) futhi isetshenziswa kuzikhali zethangi, amasudi angangenwa izinhlamvu kanye nasezinhlelweni eziningi zezimboni.Isetshenziswa ezintweni ezingagugi, isigaba esiqinisiwe se-ceramic, ikakhulukazi kuzikhali ezilula, i-reactor neutron absorbent, e.tc.

Inzuzo
1. Izinto zokugaya izinhlayiyana zezinga eliphezulu;
2. Yenza ikhemikhali yobumba, ingilazi, noma umlomo wombhobho;
3. I-reactor yenuzi kanye nezinto ezivikelayo;
4.Khiqiza izikhali ezivikela izinhlamvu;
5. Thuthukisa ukuphakanyiswa kwesevisi yezingxenye eziwumshini;
6. Njengesengezo sokugcwaliswa kwezinto zamakhemikhali e-boron;
7. Isigcwalisi esibalulekile sezinto eziphikisayo.
