Ibintu bifatika na shimi	imitungo idafite ibara rya orthorhombic kristal cyangwa ifu yera. gushonga ingingo 1580 ℃ ubucucike ugereranije 4.50 (15 ℃) solubilité hafi yo kudashonga mumazi, Ethanol na aside. Gukemura muri acide sulfurike ishyushye. idafite ibara rya orthorhombic kristal cyangwa ifu ya amorphous yera. Ubucucike bugereranije 4.50 (dogere 15 C). Ingingo yo gushonga 1580 ° c. Guhindura polycrystalline bibaho kuri 1150 ° c. Kwangirika gukomeye kwatangiye kuri 1400 ° c. Imiti ihamye. Mubyukuri bidashobora gushonga mumazi, Ethanol na acide. Gushonga muri acide sulfurike ishyushye, yumye byoroshye agglomerate. 600 C hamwe na karubone irashobora kugabanuka kuri barium sulfide.
Koresha	Ikoreshwa cyane nkibikoresho biremerera amavuta na gaze gasanzwe yo gucukura ibyondo, kandi nigikoresho cyingenzi cyamabuye y'agaciro yo gukuramo ibyuma bya bariyumu no gutegura ibibyimba bitandukanye. Ibintu byingenzi bya bariyumu mu nganda ni barium karubone, barium chloride, aside sulfurike, barium nitrate, barium hydroxide, barium oxyde, barium peroxide, barium chromate, Barium manganate, barium chlorate, lithopone, barium polysulfide, nibindi. nk'ibikoresho fatizo no kuzuza reberi, plastiki, pigment, impuzu, gukora impapuro, imyenda, amarangi, wino, electrode; Ikoreshwa nk'amavuta ashingiye kuri barium, gutunganya amavuta, isukari ya beterave, ibikoresho fatizo bya Rayon; Ikoreshwa nk'imiti yica udukoko, sterilants, rodentiside, ibisasu, icyatsi kibisi pyrotechnic, igisasu cyerekana ibimenyetso, tracer, ibipimo byerekana amafoto X-ray; Ikoreshwa kandi mubirahure, ububumbyi, uruhu, ibikoresho bya elegitoroniki, ibikoresho byubwubatsi, metallurgie nandi mashami. Ibyuma bya Barium birashobora gukoreshwa kuri tereviziyo kandi nyayo

Intangiriro

Ntabwo biryoshye, ntabwo ari uburozi. Kubora hejuru ya 1600 ℃. Gushonga muri acide ya sulfurike ishyushye, idashobora gushonga mumazi, acide organic na organic organique, igisubizo cya caustic, gushonga muri acide sulfure ishyushye hamwe na acide sulfurike ishyushye. Imiterere yimiti irahamye, kandi igabanywa kuri barium sulfide nubushyuhe hamwe na karubone. Ntabwo ihindura ibara iyo ihuye na hydrogen sulfide cyangwa imyuka yubumara yo mu kirere.
