Iron(III) oxide or ferric oxide is the inorganic compound with the formula Fe 2 O 3.It is one of the three main oxides of iron, the other two being iron(II) oxide (FeO), which is rare; and iron(II,III) oxide (Fe 3 O 4), which also occurs naturally as the mineral magnetite.As the mineral known as hematite, Fe 2 O 3 is the main source of iron for the steel industry. It is a widespread yellow pigment in continental sediments, rocks, and soils. ;&,D_8i13Es+/K_=^T) =G=.c=``=e[XQi3i4R8jVaM@21q%4#>-(hoG_mt! _>S!hHS0seGY$XOj6__pQA98^S6L`da4I1?XiE5)(`Y_GQp^:HdDS"`)EcQ)Ac>'b]_E\[PFs3r'9,2)HnR:_pL7\`70=q+AD:^0ND Vol. ()G$eMW"iIBgdD[>E!#@u\f: *E4SNk[0d+9F&XZ!>lc$YK@ZI?fqg ?.FWm5@J1c`ZKL#N\:5uEs#JW*&I\X?W,DC2./lg'Tc4%s;#n'^^FocKjQPNC]G1pC#A1_F"8 endstream endobj 34 0 obj<> endobj 35 0 obj<> endobj 36 0 obj<> endobj 37 0 obj<>stream ;mGIcJRFDS(^(NQZn8?HDnl$.IC_^rP*a99 The hematite/(hematite+ goethite) ratio, Hm/(Hm + Gt), was estimated from the area ratio of the line Hm 104 or Hm 012 to the line Gt 100, and the degree of [Al.sup.3+] substitution in hematite was calculated from the d(110) spacing (SCHWERTMANN et al., 1979) in hematite, and the d(110) and d(111) spacing in goethite (SCHULZE, 1984). 4oPrZU>jmh%@JQZ]G!3k;#;ONql'ZM89ZTlnOr5[Xd#\T2#BT1n^AhB$89;S2L#5XLX3ZkAga(W8G=]nDLn0FKK-lsV!ZFm:+J78M J,AfU3u$*jG?Rs08A?r 752 pp. _k^-)Z&S4ZBmg]5@\'S)U+Q])*3JM$\]jJ;OVB7)3;>.MgkD-/,EteYae!,S^ )&+GU)pIS,7tL[N'"aQ_ZJTH)_]a%fLkSN:-m7h[ca'Ok )U?%37snYJ:A\ ]R'&T_addlt'SYnBS0:92a4Z813 SuI7]'(27*5M5SpV@$]\>[FUl6Oqdl@1XD=P3'`2._H4Zjh#qu%XG$ONg-H@4f&WYM8j=c*#=#p • In the special case of energy dispersive diffraction, a polychromatic beam is used.
