Terras Raras, Energia, Ímãs, Fósforos luminescentes, Turbinas eólicas.Resumo
As reservas de terras raras no Brasil são re-avaliadas. Terras raras podem ser obtidas como subproduto da extração de nióbio, tântalo e estanho. As principais aplicações de terras raras são discutidas. Entres essas aplicações encontram-se ímãs, fósforos luminescentes e catálise. Uma das aplicações de maior demanda em volume são ímãs NdPrFeB para turbinas gigantes de energia eólica. Lâmpadas fluorescentes estão sendo substituídas por lâmpadas de LED, reduzindo a demanda por Európio.Downloads
