Barium sulphate, yomwe imadziwikanso kuti precipitated barium sulfate, imagwiritsidwa ntchito kwambiri. Mapangidwe ake a maselo ndi BaSO4 ndipo kulemera kwake kwa maselo ndi 233.39, zomwe zimapangitsa kuti zikhale zofunikira kwambiri m'mafakitale osiyanasiyana. Kusungidwa pansi pa kutentha kwabwino komanso chinyezi, nthawi yovomerezeka imatha mpaka zaka 2, kuwonetsetsa moyo wake wautumiki ndi kupezeka.

Chimodzi mwazinthu zazikulu zomwe zimagwiritsidwa ntchito ndi barium sulphate ndikuzindikira kuchuluka kwa nayitrogeni mu mbewu zachilala pogwiritsa ntchito njira ya barium sulphate ndi nitric acid test powder. Amagwiritsidwanso ntchito kuyeza kuchotsedwa kwa nayitrogeni m'nthaka. Kuonjezera apo, amagwiritsidwa ntchito popanga mapepala ojambula zithunzi ndi minyanga ya njovu yokumba, komanso zodzaza mphira ndi kusungunuka kwa mkuwa.

Kuphatikiza apo, barium sulfate imagwiritsidwanso ntchito popanga utoto wamagalimoto, kuphatikiza zoyambira zamagetsi, zoyambira zamitundu, ma topcoats ndi utoto wamakampani, monga utoto wazitsulo zamitundu, utoto wamba wowuma, zokutira za ufa, ndi zina zambiri. zokutira matabwa, inki zosindikizira, thermoplastics, thermosets, zomatira za elastomer ndi zosindikizira. Kusinthasintha kumeneku kumapangitsa kukhala gawo lofunikira pazogulitsa ndi zida zosiyanasiyana.

Zomwe zimapangidwira pawirizi zimapangitsa kuti zikhale zoyenera pa ntchito zosiyanasiyana. Kusakhazikika kwake, kachulukidwe kakang'ono ndi mtundu woyera kumathandizira kuti azichita bwino m'mafakitale osiyanasiyana. Ultrafine barium sulfate ndi yofunika kwambiri mu zokutira zamagalimoto ndi mafakitale, zomwe zimapereka kukhazikika komanso kutha kwapamwamba.

Mwachidule, ntchito zambiri za precipitated barium sulphate zimapangitsa kuti ikhale yofunika kwambiri pazinthu zambiri komanso njira. Ntchito zake zosiyanasiyana, kuyambira kuyesa zaulimi kupita ku zokutira zamagalimoto ndi mafakitale, zikuwonetsa kufunikira kwake pakupanga zamakono ndi machitidwe asayansi. Pamene luso lamakono ndi zatsopano zikupitirirabe patsogolo, kufunikira kwa barium sulphate kuyenera kukula, kulimbitsa malo ake monga chinthu chofunika kwambiri m'mafakitale.
