Barium Carbonate
Cov ntxhia tau muaj npe tom qab William Withering, uas nyob rau xyoo 1784 paub tias nws yuav tsum sib txawv ntawm barytes. Nws tshwm sim hauv cov leeg ntawm cov hlau lead ntawm Hexham hauv Northumberland, Alston hauv Cumbria, Anglezarke, ze Chorley hauv Lancashire thiab ob peb lwm thaj chaw. Witherite yog qhov yooj yim hloov rau barium sulfate los ntawm qhov kev ua ntawm cov dej uas muaj calcium sulfate hauv kev daws thiab muaju muaj feem ntau yog li nquag siv nrog barytes. Nws yog lub hauv paus loj ntawm barium ntsev thiab yog mined hauv kev txiav txim siab hauv Northumberland. Nws yog siv rau kev npaj cov tshuaj lom nas, hauv kev tsim cov iav thiab plooj (veneers), thiab yav dhau los ua kom cov ntshav qab zib. Nws tseem siv rau kev tswj cov chromate rau sulfate piv hauv chromium electroplating da dej.
