Descripci\u00f3: El lignit Carb\u00f3 f\u00f2ssil de formaci\u00f3 m\u00e9s recent que la hulla. \u00c9s un combustible de qualitat interm\u00e8dia entre el carb\u00f3 de torba i el carb\u00f3 bitumin\u00f3s, del tipus h\u00famic ric en humina i en \u00e0cids h\u00famics. S’hi poden recon\u00e8ixer microsc\u00f2picament restes de fusta, de fulles i de fruits.Procedeix de la fossilitzaci\u00f3 de restes org\u00e0niques vegetals.
\nLa seva composici\u00f3 qu\u00edmica es (60-75% de carboni).
\nPer les seves caracter\u00edstiques, es distingeixen els seg\u00fcents tipus de lignits: marr\u00f3-terrosos o fibrosos (els m\u00e9s pr\u00f2xims a les torbes en aspecte i propietats, de color marr\u00f3 clar i textura fibrosa), llenyosos o xifoide (de color marr\u00f3 clar i amb aspecte lleny\u00f3s , constitu\u00efts per fusta carbonificada l’estructura conserva; en molts carbons bruns s’observen bandes de lignit xiloide), carbons marrons amorfs (sense reserva de fibres vegetals).<\/p>\n
Aquest material \u00e9s susceptible de poliment, obtenint peces d’extrema bellesa i que en l’antiguitat van ser apreciades com adorns. <\/p>\n
Era Terci\u00e0ria \u00e9s l’era geol\u00f2gica que es va iniciar fa 65,5 milions d’anys i que s’est\u00e9n fins a l’actualitat. Era de la desaparici\u00f3 dels dinosaures. L’era Secund\u00e0ria es va iniciar fa 251,0 milions d’anys i va finalitzar al comen\u00e7ament de l’era Terci\u00e0ria. L’era dels dinosaures.<\/p>\n
La cera de lignit \u00e9s generalment utilitzada en diverses ind\u00fastries per crear:<\/p>\n
– Ceres per a acte
\n– Ceres per a cal\u00e7at
\n– Pintures diferents
\n– Discos fonogr\u00e0fics
\n– Lubricants per al paper
\n– Pl\u00e0stics<\/p>\n
