Malunga I-Barium
I-barium iyinsimbi eqinile, emhlophe, eqinile, engatholakali emvelo. I-barium sulfate isetshenziswa njenge-radiocontrast agent ye-digestion X-rays. I-barium compounds ikhiqiza amamibala aluhlaza okwesibhakabhaka emicimbini yezikhali.
Izisebenziso
Ukukhiqizwa kwezithombe ze-X-ray zezokwelapha, ama-fluids okukhipha i-oyile, ama-fireworks (imibala eluhlaza), iglasi, kanye ne-poisons yezinhlanzi.
Iqiniso elijabulisayo
Abaguli badla i-barium sulfate ngaphambi kokuhlolwa kwe-X-ray -- i-barium iyingozi, kodwa i-sulfate ingekho emthethweni futhi idlula ngokuphephile.
