Definition of Barium
The name is derived from the Greek barys barium ( βαρύς ) , which means " heavy " . This illustrates the high density of some common barium -containing ores . The amount of barium is 0.0425 % in the Earth's crust and 13 ug / L in seawater .
Barium ( Ba ) including heavy metals such as lead white silver . Barium is an alkaline earth metal one . Barium metal surface covered with a thin layer of oxide that helps protect the metal from air attack . Barium is a metallic chemical element that resembles calcium but more reactive . Barium is never found in nature in its pure form due to its reactivity or rapidly oxidizes in air . Barium also react with water and carbon dioxide and is not found as a mineral . Barium is most commonly found as Barite ( BaSO 4 ) and witherite ( Baco 3 ) .
Metals are mainly found in , and retrieved from , Barite . Because it is so late , it can not be used directly for the preparation of
other barium compounds , or barium metal . In contrast , ore is heated with carbon to reduce it to barium sulfide :
Barium impact
Heavy metal is resistant to dust , dust resistant properties that causes increasingly heavy metals accumulate in the waters . Heavy metals in the water can get into the human body , either directly or indirectly . Heavy metals in the water may enter directly into the human body when water containing heavy metals drunk , while indirectly when eating food that comes from the water . In the human body , heavy metals can also accumulate and cause various health hazards . Dangers of barium ( Ba ) to human health , namely , in the form of powders , flammable at room temperature . In the long run , can cause a rise in blood pressure and disruption of the nervous system .
All water or acid soluble barium compounds are poisonous. At low doses , barium acts as a muscle stimulant , while higher doses affect the nervous system , causing cardiac irregularities , tumors , weakness , anxiety , dyspnea and paralysis . This may be due to its ability to block potassium ion channels which are essential for the proper function of the nervous system
Barium compounds , are rarely encountered by most people . All barium compounds are considered very toxic although initial evidence appears to indicate the danger is limited . Barium salt can damage the liver . Inhalation of dust containing barium compounds can accumulate in the lungs , causing a condition called baritosis . Metal dust presents a fire and explosion hazard , and barium powder can ignite spontaneously in air .
Metal barium should be kept under a petroleum -based fluid ( such as kerosene ) or other suitable oxygen - free liquids that emit air .
