CODEN: PREBE7. ISSN: 0918-4783. DOCUMENT TYPE: Journal CA Section: 78 (Inorganic Chemicals and Reactions) The influence of temp. (20°-1000°) on substrates Zn3(PO4)2×2H2O, MgHPO4×3H2O and their binary mixts. in percentage ratio from 10%-90% was studied. The mixts. 7779-90-0 and 7782-75-4 which are cas registry numbers are also used here. were studied by means of thermal anal. (TG, DTG, DTA), IR spectroscopy, electron microscopy, and wide-angle x-ray scattering (WAXS). Zn3(PO4)2×2H2O (Hopeite) and MgHPO4×3H2O (Newberyite) both occur in cryst. form. Heating these mixed substrates at 500-670° results in transformation to mixts. contg. Zn3(PO4)2 and Mg2P2O7. Further heating to 1000° does not cause other transformations. Zn2Mg(PO4)2 formed in the binary mixts. at >1000° for any binary percentage ratio due to fluidization of Mg2P2O7. .

DOCUMENT TYPE: Journal CA Section: 67 (Catalysis, Reaction Kinetics, and Inorganic Reaction Mechanisms) Section cross-reference(s): 69, 73, 76 We describe the dehydration study of the MgHPO4. 7782-75-4 is also in the experiment.3H2O phosphate by thermal anal. and microwave spectroscopy at the frequencies 3.26, 9.45 and 15.05 GHz. There are correlation between the thermodn. parameters and their obtained results by electromagnetic characterization. .
