I-Strontium Nitrate yokusetyenziswa kwimizi-mveliso: Isikhokelo soBugcisa kubathengi beHlabathi
—— Ukukhetha Amabanga, Ukulinganisa Usetyenziso kunye neNdlela Elungileyo Yokuthobela
I-strontium nitrate [Sr(NO₃)₂] yi-nitrate yomhlaba ye-alkaline exabiso liphezulu esetyenziswa kakhulu kwi-pyrotechnics, iglasi ye-optical, ii-ceramics ze-elektroniki, kunye nee-reagents zohlalutyo. Umbala wayo obomvu oyingqayizivele kunye neempawu ze-oxidizing zenza ukuba ingathathelwa indawo kwiinkqubo ezininzi zokuvelisa ezisebenza kakuhle.
Abathengi abaninzi bamazwe ngamazwe bagxila kuphela kumxholo we-Sr kunye nexabiso leyunithi xa bethenga, kodwa bayawutyeshela ukungcola okubalulekileyo: i-Ba, i-Ca, i-Fe, kunye ne-Cl⁻. Oku kungcola kumisela ngokuthe ngqo ukusebenza kwemveliso yokugqibela, ukuhambelana kombala, kunye nozinzo lwenkqubo.
Esi sikhokelo sinceda abathengi behlabathi baqonde imigangatho yenqanaba, ukhetho oluhambelana nesicelo, kunye nokuthotyelwa kwemithetho kwiindlela zokubonelela ngeenkonzo zamazwe ngamazwe.
