보크사이트

보크사이트(프랑스어: bauxite 보크사이트[*]) 또는 철반석(鐵礬石)은 퇴적암의 일종으로, 알루미늄갈륨을 주로 여기서 추출한다. 알루미늄이 들어간 깁사이트(gibbsite, Al(OH)3), 뵈마이트(boehmite, γ-AlO(OH)), 다이아스포어(diaspore, α-AlO(OH)) 등의 물질로 구성되며, 침철석적철석, 고령석도 함유되어 있다.[1]

1821년 프랑스지질학자인 피에르 베르티에가 프로방스레보(Les Baux)에서 발견했기에 이런 이름이 붙여졌다.[2][3]

오스트레일리아, 중국, 기니, 브라질에서 주로 생산된다.[1]

    • In 1847, in the cumulative index of volume 3 of his series, Traité de minéralogie, French mineralogist Armand Dufrénoy listed the hydrated alumina from Les Beaux as "beauxite". (See: A. Dufrénoy, Traité de minéralogie, volume 3 (Paris, France: Carilian-Goeury et Vor Dalmont, 1847), p. 799.)
    • In 1861, H. Sainte-Claire Deville credits Berthier with naming "bauxite", on p. 309, "Chapitre 1. Minerais alumineux ou bauxite" of: H. Sainte-Claire Deville (1861) "De la présence du vanadium dans un minerai alumineux du midi de la France. Études analytiques sur les matières alumineuses."
