Ohun elo

Barium jẹ ẹya kemikali ti o ni aami Ba ati nọmba atomiki 56. O jẹ ipin karun ninu Ẹgbẹ 2, irin ti o jẹ fadaka ti fadaka.Nitori ifaseyin kemikali giga rẹ, a ko rii barium rara ni iseda bi eroja ọfẹ.

Awọn ohun elo: Irin ati awọn ohun elo, awọn ohun elo ti o niiṣe;lead–tin soldering alloys – lati mu awọn ti nrakò resistance;alloy pẹlu nickel fun sipaki plugs;aropo si irin ati simẹnti irin bi inoculant;awọn alloys pẹlu kalisiomu, manganese, silikoni, ati aluminiomu bi awọn deoxidizers irin giga-giga.Barium ni awọn ohun elo ile-iṣẹ diẹ nikan.Awọn irin ti a ti itan lo lati scavenge air ni igbale Falopiani.O jẹ paati ti YBCO (awọn superconductors iwọn otutu giga) ati awọn ohun elo elekitiro, ati pe a fi kun si irin ati simẹnti irin lati dinku iwọn awọn irugbin erogba laarin microstructure ti irin naa.
