Um metal refrat\u00e1rio com propriedades el\u00e9ctricas, qu\u00edmicas e f\u00edsicas \u00fanicas, utilizado principalmente como p\u00f3 met\u00e1lico de t\u00e2ntalo na produ\u00e7\u00e3o de componentes electr\u00f3nicos, sobretudo condensadores de t\u00e2ntalo. Como tem um ponto de fus\u00e3o muito elevado, \u00e9 ligado a outros metais para criar ligas que s\u00e3o necess\u00e1rias para aplica\u00e7\u00f5es a temperaturas muito elevadas, como equipamento para trabalhar metais e componentes de motores a jato.<\/p>\n

Uma vez que o t\u00e2ntalo \u00e9 t\u00e3o resistente \u00e0 corros\u00e3o, \u00e9 utilizado para fabricar instrumentos cir\u00fargicos e equipamento m\u00e9dico, como hastes para fixar ossos partidos, placas cranianas e malhas de arame para ajudar a reparar nervos e m\u00fasculos.<\/p>\n

O t\u00e2ntalo \u00e9 tamb\u00e9m utilizado em lentes de c\u00e2maras.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n
