InamaI-Barium sulfate(BaSO4), i-EINECS No. 231-784-4, iyinhlanganisela efunwa kakhulu eyaziwa ngokuhlanzeka kwayo okuyingqayizivele, okungenani i-98% ye-BaSO4. Leli khemikhali elishintshashintshashintshayo lisetshenziswa ezimbonini eziningi ezihlanganisa amapende, ama-coatings ngisho nokukhiqiza amabhethri. Izakhiwo zayo eziyingqayizivele ziyenza ibe isithako esibalulekile ezinhlelweni eziningi, iqinisekisa imiphumela yekhwalithi ephezulu.

Esinye sezici ezivelele ze-barium sulfate encishisiwe yikhono layo lokukhiqizwa ngezinga elikhulu. Abakhiqizi banezinqubo ezithuthukisiwe zokuqinisekisa ukulethwa okusheshayo ngaphandle kokubeka engcupheni ikhwalithi. Lokhu kusebenza kahle kubalulekile embonini ethembele ochungechungeni lokuhlinzekwa kwempahla olufika ngesikhathi ukuze ihlangabezane nezidingo zokukhiqiza. Noma ngabe iphrojekthi yokumboza yezinga elikhulu noma uhlelo lokusebenza lwebhethri olukhethekile, ukunikezwa kwekhwalithi ephezulu ye-barium sulfate kuyashintsha umdlalo.

I-Barium sulfate iyi-pigment ebalulekile kanye nesigcwalisi embonini kapende nezingubo. Ngefomula ye-molecular ye-BaSO4, ithuthukisa ukukhanya nokuqina kopende, inikeze indawo enhle nehlala isikhathi eside ebushelelezi. Ukwengeza, ukuzinza kwayo kwamakhemikhali kuqinisekisa ukuthi ngeke kusabele kabi nezinye izithako, okwenza kube ukukhetha okuthembekile kwabakhi.

Ngaphezu kwalokho, ukusetshenziswa kwe-barium sulfate ekukhiqizeni ibhethri kugqamisa ukuguquguquka kwayo. Njenge-chemical sulfate, isiza ukuthuthukisa ukusebenza kahle nokusebenza kwamabhethri, okwenza kube yingxenye ebalulekile yezixazululo zamandla zanamuhla.

Sengiphetha, i-barium sulfate encishisiwe ingaphezu nje kwenhlanganisela, iyitshe legumbi lezimboni ezihlukahlukene. Ngokuhlanzeka kwayo okuphezulu, amandla amakhulu okukhiqiza kanye nezinhlelo zokusebenza ezihlukahlukene, i-BaSO4 iyaqhubeka nokubamba iqhaza elibalulekile ekuthuthukisweni kwezobuchwepheshe kanye nokwenza ngcono izinga lomkhiqizo. Njengoba imboni ithuthuka, isidingo sekhwalithi ephezulu ye-barium sulfate ngokungangabazeki sizokhula, sihlanganise isikhundla saso emakethe.
