Barium warowaihā, tātai matū BaCO3, taumaha rāpoi 197.336. Te paura ma. Karekau ki te wai, kiato 4.43g/cm3, ira whakarewa 881℃. Ko te pirau i te 1450 ° C ka tukuna te hauhā. He iti te wairewa i roto i te wai kei roto te waro hauhā, engari ka whakarewahia ano ki te haukinia pūhaumāota, haukinia pākawa wairewa ki te hanga i te matatini, wairewa i roto i te waikawa pūmāota, waikawa nitric ki te tuku hauhāhā. He paitini. Whakamahia i roto i te hikohiko, taputapu, ahumahi whakarewa. Te whakaritenga o te ahi, te hanga anga tohu, te paninga uku, nga taputapu karaihe whatu. Ka whakamahia ano he rodenticide, he whakamaarama wai me te whakakii.
He pūhui pararopi nui te Barium carbonate me te tātai matū BaCO3. He paura ma e kore e rewa ki te wai engari he ngawari te rewa ki nga waikawa kaha. Kei te whakamahia nuitia tenei puhui maha i roto i nga momo ahumahi na ona ahuatanga ahurei.
Ko te taumaha ngota o te barium warowaiha he 197.336. He paura ma pai me te kiato o te 4.43g/cm3. He 881°C te ira whakarewa, ka pirau i te 1450°C, ka puta te hauhā. Ahakoa he ngoikore te wairewa ki te wai, he iti te wairewa i roto i te wai kei roto i te waro hauhā. Ka taea hoki te hanga matatini, ka whakarewahia ki te haukinia pūhaumāota wairewa haukinia pākawa rānei. I tua atu, he ngawari te wairewa i roto i te waikawa waikawa me te waikawa nitric, ka tuku i te waro hauhā.
