XRD Analysis

40 kV - 30 mA, 7.3-9.5 keV File: amjarscf.out, -.mdi References: JCPDS 26-1014; Huebner's reference patterns Found : ammoniojarosite Comment: strong pattern, sharp peaks, very well crystallized, excellent match to the JCPDS pattern. A very weak, probably significant reflection at 2.356A does not appear on the JCPDS card. J.S. Huebner, J. Pickrell, T. Schaefer, written communication 1994
