Cim npe

Cov ntxhia muaj npe tom qab William Withering, uas nyob rau xyoo 1784 tau lees paub tias nws yog cov tshuaj sib txawv ntawm barytes. Nws tshwm sim hauv cov hlab ntsha ntawm cov hlau lead ntawm Hexham hauv Northumberland, Alston hauv Cumbria, Anglezarke, ze Chorley hauv Lancashire thiab ob peb lwm qhov chaw. Witherite tau hloov pauv mus rau barium sulfate los ntawm kev ua ntawm cov dej uas muaj calcium sulfate hauv cov tshuaj thiab cov muaju yog li feem ntau encrusted nrog barytes. Nws yog qhov tseem ceeb ntawm cov ntsev barium thiab yog mined ntau npaum li cas hauv Northumberland. Nws yog siv rau kev npaj cov tshuaj lom nas, hauv kev tsim cov iav thiab cov plooj (porcelain), thiab yav tas los rau refining qab zib.Nws kuj yog siv los tswj cov chromate rau sulfate piv hauv chromium electroplating da dej.
