Characterization of Taranakites and Ammonium Aluminum Phosphates¹

ABSTRACT

Optical, X-ray diffraction, infrared absorption, and differential thermal analysis data are presented for the salts K₃Al₅H₆ (PO₄)₈·18H₂O, (NH₄)₃Al₅H₆(PO₄)₃·18H₂O, (NH₄)₂AlH(PO₄)₂·4H₂O, NH₄AlPO₄OH·2H₂O, and NH₄AlPO₄OH·3H₂O. Where the particle size is too small for determination of optical characteristics, a combination of X-ray diffraction and infrared absorption methods is the most satisfactory means of identification of these compounds. Differential thermal analysis is unsuitable for the ammonium salts.
