QUÉ SIGNIFICA BARIUM EN INGLÉS
Bario
El bario es un elemento químico con el símbolo Ba y el número atómico 56. Es el quinto elemento en el grupo 2, un metal alcalino-metalino plateado suave. Debido a su alta reactividad química el bario nunca se encuentra en la naturaleza como un elemento libre. Su hidróxido era conocido en la historia pre-moderna como baryta; Esta sustancia no se presenta como un mineral, pero puede prepararse calentando carbonato de bario. Los minerales naturales más comunes del bario son barita y witherite, siendo ambos insolubles en agua. El nombre del bario se origina del derivado alquímico "baryta", que viene del griego βαρύς, que significa "pesado". El bario se identificó como un nuevo elemento en 1774, pero no se redujo a un metal hasta 1808, poco después de que las técnicas de aislamiento electrolítico estuvieran disponibles. El bario tiene sólo unas pocas aplicaciones industriales. El metal se ha utilizado históricamente para limpiar el aire en tubos de vacío. Es un componente de YBCO y electrocerámica, y se añade a acero y hierro fundido para reducir el tamaño de los granos de carbono dentro de la microestructura del metal. Los compuestos de bario se añaden a los fuegos artificiales para impartir un color verde.
