O corindo \u00e9 uma forma cristalina de \u00f3xido de alum\u00ednio (Al2O3) com vest\u00edgios de ferro, tit\u00e2nio e cr\u00f3mio. \u00c9 um mineral formador de rocha. \u00c9 um dos materiais naturalmente transparentes, mas pode ter cores diferentes quando as impurezas est\u00e3o presentes. Os esp\u00e9cimes transparentes s\u00e3o utilizados como gemas, como safiras e rubis. Os rubis s\u00e3o vermelhos devido a vest\u00edgios de cr\u00f3mio no corindo. Todas as outras cores de corindo transparente s\u00e3o chamadas safiras. As safiras azuis profundas s\u00e3o azuis devido \u00e0 presen\u00e7a de tit\u00e2nio e ferro.<\/p>\n

O corindo sint\u00e9tico foi criado pela primeira vez em 1837 e em 1903 o fabrico de corindo tornou-se numa escala mais alargada. Originalmente sintetizado para fabricar rubis, atualmente o corindo \u00e9 sintetizado para fabricar lentes para sat\u00e9lites, vidro resistente a riscos e outros materiais \u00f3pticos de elevada resist\u00eancia.<\/p>\n

Geologia: O corindo \u00e9 uma variante metam\u00f3rfica da bauxite e, por isso, aparece mais frequentemente como um dep\u00f3sito de bauxite metamorfoseada ou como xisto aluminoso alterado. \u00c9 invulgarmente denso e quase t\u00e3o duro como o diamante. O corindo de qualidade de gema \u00e9 encontrado em cursos de \u00e1gua, uma vez que a sua elevada densidade faz com que as pe\u00e7as se depositem numa regi\u00e3o local e a sua dureza torna-o resistente \u00e0 meteoriza\u00e7\u00e3o.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n

O corindo \u00e9 utilizado como abrasivo porque tem uma dureza de 9,0 e pode riscar quase tudo. \u00c9 utilizado em lixas e em abrasivos industriais. No entanto, nos EUA, os sint\u00e9ticos come\u00e7aram recentemente a substituir o corindo natural como abrasivo de elei\u00e7\u00e3o. A sua maior utiliza\u00e7\u00e3o nos EUA \u00e9 para endurecer pavimentos de bet\u00e3o pesado e para material antiderrapante em pontes. Devido ao facto de o corindo sint\u00e9tico ser t\u00e3o duro e tamb\u00e9m transparente, tem muitas aplica\u00e7\u00f5es na \u00f3tica e no equipamento espacial.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n
