Iinkcukacha

Iithegi

Iminerali ithiywe ngoWilliam Withering, owathi ngo-1784 waqaphela ukuba yahlukile ngokwekhemikhali kwi-barytes. Yenzeka kwimithambo yentsimbi ekrwada eHexham eNorthumberland, eAlston eCumbria, eAnglezarke, kufutshane neChorley eLancashire nakwezinye iindawo ezimbalwa. I-Witherite iguqulwa ngokukhawuleza kwi-barium sulfate ngesenzo samanzi aqukethe i-calcium sulfate kwisisombululo kunye neekristale ngoko ke zihlala zifakwe kwi-barytes. Ngoyena mthombo oyintloko wetyuwa ye-barium kwaye yombiwa ngezixa-mali ezininzi e-Northumberland. Isetyenziselwa ukulungiswa kwetyhefu yeempuku, ekwenzeni iglasi kunye ne-porcelain, kwaye ngaphambili ekuphuculeni iswekile.Ikwasetyenziselwa ukulawula umlinganiselo wechromate kwisulfate kwiibhafu ze-chromium electroplating.
