Izakhiwo Zomzimba Nezamakhemikhali izakhiwo zekristalu ye-orthorhombic engenambala noma impushana emise okumhlophe.
indawo encibilikayo 1580 ℃
ukuminyana okuhlobene 4.50(15 ℃)
I-solubility cishe ayincibiliki emanzini, ethanol ne-asidi. Incibilika ku-asidi e-sulfuric egxilile eshisayo.
i-orthorhombic crystal engenambala noma i-amorphous powder emhlophe. Ukuminyana okuhlobene 4.50 (15 degrees C). Iphuzu lokuncibilika 1580 °c. Ukuguqulwa kwe-polycrystalline kwenzeka cishe ku-1150 °c. Ukubola okubalulekile kwaqala cishe ku-1400 °c. Ukuzinza kwamakhemikhali. Ayincibiliki emanzini, i-ethanol nama-asidi. Incibilika ku-asidi e-sulfuric egxilile eshisayo, yomile kalula ukuhlanganisa. I-600 C enekhabhoni ingancishiswa ibe yi-barium sulfide.
Sebenzisa Isetshenziswa kakhulu njenge-ejenti yokulinganisa udaka lukawoyela negesi yemvelo yokumba, futhi ibuye ibe yimpahla eluhlaza yamaminerali ebalulekile yokukhipha i-barium yensimbi nokulungiselela izinhlanganisela ezahlukahlukene ze-barium. Izinhlanganisela ze-barium ezibaluleke kakhulu embonini yi-barium carbonate, i-barium chloride, i-sulfuric acid, i-barium nitrate, i-barium hydroxide, i-barium oxide, i-barium peroxide, i-barium chromate, i-barium manganate, i-barium chlorate, i-lithopone, i-barium polysulfide, njll. Izinhlanganisela ze-barium zisetshenziswa kabanzi njengezinto zokusetshenziswa kanye nezigcwalisi zenjoloba, amapulasitiki, izingulube, okokuhlanganisa, ukwenza amaphepha, izindwangu, amapende, oyinki, ama-electrode; Isetshenziswa njenge-barium-based grease, ukucwenga uwoyela, ushukela webhitrudi, izinto zokusetshenziswa zeRayon; Isetshenziswa njengezibulala-zinambuzane, ama-sterilants, ama-rodenticides, iziqhumane, i-Green pyrotechnic, ibhomu lesignali, i-tracer, izinkomba ze-X-ray zezokwelapha; Ibuye isetshenziswe engilazini, i-ceramics, isikhumba, i-electronics, izinto zokwakha, i-metallurgy neminye iminyango. Insimbi ye-barium ingasetshenziselwa ithelevishini kanye neqiniso

Izimpawu Eziyingozi I-Xn - Iyingozi
Amakhodi Engozi R20/21/22 – Kuyingozi ngokuhogela umoya, ukuthintana nesikhumba futhi uma ukugwinyile.
R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba.
Incazelo Yokuphepha S22 - Ungaphefumuli uthuli.
I-S24/25 - Gwema ukuthintana nesikhumba namehlo.
S36 – Gqoka izingubo ezifanele zokuzivikela.
S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha.

Isingeniso

Okunganambitheki, okungeyona ubuthi. Ukubola ngaphezu kuka-1600 ℃. I-soluble ku-hot concentrated sulfuric acid, ayincibiliki emanzini, ama-organic kanye nama-inorganic acid, isixazululo se-caustic, encibilika ku-acid e-sulfurous eshisayo kanye ne-sulfuric concentrated sulfuric acid. Izakhiwo zamakhemikhali zizinzile, futhi zehliselwa ku-barium sulfide ngokushisa nekhabhoni. Ayishintshi umbala lapho ichayeke ku-hydrogen sulfide noma amagesi anobuthi emoyeni.
