Preparation and Luminescence of Selected Eu3+-Activated Rare Earth-Oxygen-Sulfur Compounds

Journal of The Electrochemical Society (1968)

James Haynes Jesse J. Brown

The hydrated sulfate, sulfate, oxysulfate, and oxysulfide compounds of yttrium, lanthanum, gadolinium, and lutetium were prepared using precipitation techniques and controlled atmosphere high temperature heat treatments. The temperature stability range in air for each compound was investigated by DTA and TGA methods. X‐ray diffraction powder data are presented for the fourteen compounds isolated. The only compounds that showed significant Eu3+‐activated luminescence were the oxy sulfates and oxysulfides. , the most efficient phosphor examined, is as bright as and distinctly more "red." Luminescence data are presented and discussed.

Phase Equilibria in the System CaF₂‐AlF₃‐Na₃AlF₆ and Part of the System CaF₂‐AlF₃‐Na₃AlF₆‐Al₂O₃

Journal of the American Ceramic Society (1980)

Douglas F. Craig Jesse J. Brown

The complete phase‐equilibrium diagram of the system CaF 2 ‐AlF 3 ‐Na 3 AlF 6 and the subsolidus portion of the system CaF 2 ‐AlF 3 ‐Na 3 AlF 6 ‐Al 2 O 3 were established from microscopic, powder X‐ray diffraction, quench, and DTA data obtained from samples encapsulated in sealed tubes and either reacted in the solid state or melted and recrystallized. The system Na 3 AlF 6 ‐CaF 2 contains a simple eutectic with no compound formation or solid solution. The system CaF 2 ‐AlF 3 ‐Na 3 AlF 6 contains two ternary compounds, NaCaAlF 6 and NaCaAl 2 F 9 , which melt incongruently at 735° and 712°C, respectively; NaCaAlF 6 exists in three polymorphic forms with transitions at 610° and 722°C and NaCaAl 2 F 9 is body‐centered cubic with a 0 = 10.765 Å. The three binary and two ternary compounds divide the system into eight compatibility triangles. Along the NaCaAlF 6 ‐Na 3 AlF 6 join, 7 mol% NaCaAlF 6 is soluble in α‐cryolite at 525° and 42% in β‐cryolite at 731°C. The quaternary system Na 3 AlF 6 ‐AlF 3 ‐CaF 2 ‐Al 2 O 3 contains eight compatibility tetrahedra.

In Situ Whisker‐Reinforced AlPO₄‐Modified β‐Eucryptite Glass‐Ceramic: I, Morphology and Crystallization Kinetics

Journal of the American Ceramic Society (1996)

Kyoung Ho Lee Deidre A. Hirschfeld Jesse J. Brown

A whisker‐reinforced glass‐ceramic composite in the Li 2 O‐Al 2 O 3 ‐SiO 2 ‐P 2 O 5 system has been fabricated by a single‐stage process that simultaneously forms the glass‐ceramic material and whiskers of TiO 2 in situ . The method utilizes typical glass‐ceramic processing techniques and requires precise addition of a TiO 2 nucleation agent during the glass‐melting operation, followed by controlled nucleation and crystallization. The maximum nucleation temperature, 740°C, was determined by differential thermal analysis (DTA), and the result was confirmed by scanning electron microscopy (SEM) of the microstructures formed by nucleation/isothermal crystallization heat treatments. The apparent activation energy for crystallization of the material was determined to be 285 ± 3 kj/mol. The average aspect ratio of the TiO 2 whiskers depends on temperature and time during crystallization. The X‐ray diffraction patterns of the in situ composite show that eucryptite(ss) and rutile exist as two different phases; no additional phases were observed. Elemental X‐ray mapping by electron microprobe indicates that these highly crystallized composites consist of modified β‐eucryptite glass‐ceramic matrix and acicular grains of TiO 2 .
