TITLE: Ammonium_Chloride GDS77 DESCRIPT
DOCUMENTATION_FORMAT: MINERAL
SAMPLE_ID: GDS77
MINERAL_TYPE: Chloride
MINERAL: Ammonium_Chloride
FORMULA: NH4Cl
FORMULA_HTML: NH4Cl
COLLECTION_LOCALITY: Baker Analyzed Reagent

SAMPLE_DESCRIPTION:
END_SAMPLE_DESCRIPTION.
XRD_ANALYSIS:
40 kV - 30 mA, 6.5-9.5 keV
File: amchlr77_mdi
References: PDF2 #07-0007
Found: Salammoniac
Comments: Peaks have sharp tops but are slightly broadened; resolution of the
alpha1-alpha2 components is only fair. Search-match confirms the identification
as salammoniac (NH4Cl). The sample is primitive cubic with cell edge 3.87 angstroms,
the same end member composition. The (110) at 2.73 angstroms has an unexplained,
but very weak, shoulder extending to 2.83 angstroms.
