IiPropati zoMzimba kunye nezeMichiza iipropati ezingenambala ikristale ye-orthorhombic okanye umgubo omhlophe omile.
indawo yokunyibilika 1580 ℃
Uxinzelelo olunxulumeneyo 4.50(15 ℃)
Ukunyibilika kuphantse kunganyibiliki emanzini, ethanol nakwiasidi. Inyibilika kwiasidi yesulfuric egxininisiweyo.
ikristale ye-orthorhombic engenambala okanye umgubo omhlophe we-amorphous. Ukuxinana kobudlelwane 4.50 (15 degrees C). Indawo yokunyibilika 1580 °c. Utshintsho lwePolycrystalline lwenzeka malunga ne-1150 °c. Ukubola okubalulekileyo kwaqala malunga ne-1400 °c. Uzinzo lweMichiza. Ngokuqhelekileyo ayinyibiliki emanzini, ethanol kunye neeasidi. Inyibilika kwi-asidi yesulfuric egxininisiweyo eshushu, yome lula ukuba i-agglomerate. I-600 C kunye nekhabhoni inokuncitshiswa kwi-barium sulfide.
Sebenzisa Isetyenziswa kakhulu njenge-agent yokulinganisa i-oyile kunye negesi yendalo yokwemba udaka, kwaye ikwayinto ebalulekileyo ye-mineral ekrwada yokukhupha i-barium yensimbi kunye nokulungiselela iikhompawundi ezahlukeneyo ze-barium. Iikhompawundi ze-barium ezibaluleke kakhulu kwishishini yi-barium carbonate, i-barium chloride, i-sulfuric acid, i-nitrate ye-barium, i-barium hydroxide, i-barium oxide, i-barium peroxide, i-barium chromate, i-barium manganate, i-barium chlorate, i-lithopone, i-barium polysulfide, njl njl. njengezinto ezikrwada kunye nezigcwalisi zerabha, iiplastiki, ii-pigments, iingubo, ukwenza iphepha, iingubo, iipeyinti, i-inki, i-electrode; Isetyenziswe njengegrisi esekwe kwi-barium, ukucocwa kweoyile, iswekile yebeet, imathiriyeli ekrwada yeRayon; Isetyenziswa njengezibulali-zinambuzane, izibulali-zinambuzane, izibulala-zintsholongwane, iziqhushumbisi, i-Green pyrotechnic, ibhombu yomqondiso, i-tracer, izalathi zokufota ze-X-ray zonyango; Ikwasetyenziswa kwiglasi, iiseramikhi, ngethwathwa, i-electronics, izinto zokwakha, isinyithi kunye namanye amasebe. Intsimbi yeBarium ingasetyenziselwa umabonwakude kunye nenyani

Intshayelelo

Ayinancasa, ayinayo ityhefu. Ukubola ngaphezu kwe-1600 ℃. Inyibilika kwi-asidi ye-sulfuric eshushu, ayinyibiliki emanzini, i-organic kunye ne-inorganic acids, isisombululo se-caustic, i-soluble kwi-asidi yesulfure eshushu kunye ne-asidi ye-sulfuric. Iimpawu zeekhemikhali zizinzile, kwaye ziyancipha kwi-barium sulfide ngokushisa ngekhabhoni. Ayitshintshi umbala xa ibekwe kwihydrogen sulfide okanye iigesi ezinetyhefu emoyeni.
