\"notas-terrasraras\"<\/a>Pesquisadores do Laborat\u00f3rio Nacional Oak Ridge (ORNL), ligado ao\u00a0Departamento de Energia norte-americano, em parceria com o Laborat\u00f3rio\u00a0Nacional Lawrence Livermore e a Eck Industries, desenvolveram uma liga de\u00a0alum\u00ednio com c\u00e9rio, \u00f3xido de terras raras (OTR), com baixo custo de produ\u00e7\u00e3o, alta maleabilidade, menor exig\u00eancia de tratamento t\u00e9rmico e grande estabilidade sob alt\u00edssimas temperaturas. O material \u00e9 indicado para a fabrica\u00e7\u00e3o de modelos mais leves de motores de combust\u00e3o interna ou como substituto de seus componentes de ferro fundido, caixas de transmiss\u00e3o e cabe\u00e7otes (foto).<\/p>\n

Essa aplica\u00e7\u00e3o, se adotada em escala pela ind\u00fastria de motores, tem ainda\u00a0um ganho adicional: viabilizar economicamente a produ\u00e7\u00e3o de terras raras. 0 c\u00e9rio juntamente com o lant\u00e2nio – \u00e9 o elemento de maior quantidade presente nesses min\u00e9rios (tr\u00eas vezes mais que neod\u00edmio e 500 vezes mais que dispr\u00f3sio, utilizados na fabrica\u00e7\u00e3o de Im\u00e3s) e, sem ter uma destina\u00e7\u00e3o industrial, geraria elevados volumes de rejeito. Para atender a apenas 1% da produ\u00e7\u00e3o atual de ligas de alum\u00ednio, s\u00e3o necess\u00e1rias 3 mil t de c\u00e9rio.<\/p>\n","protected":false},"excerpt":{"rendered":"
