Synthesis of Bulk, Dense, Nanocrystalline Yttrium Aluminum Garnet from Amorphous Powders

Yttrium Aluminum Garnet Fibers from Metalloorganic Precursors

Mixtures of yttrium acetate hydrate (Y(O2CCH3)3?4H2O) and aluminum formate hydrate (Al(O2CH)3?3H2O in H2O) or yttrium isobutyrate (Y[O2CCH(CH3)2]3) and aluminum isobutyrate (Al[O2CCH(CH3)2]3) in tetrahydrofuran were used as precursors to process yttrium aluminum garnet (YAG, Al5Y3O12) fibers. The pyrolytic decomposition patterns of Al(O2CH)3?3H2O, Y(O2CCH3)3?4H2O, and a [3Y(O2CCH3)3?4H2O/5Al(O2...

Effect of Synthesis Temperature on the Electrochemical Properties of Yttrium Aluminum Garnet

In this study, yttrium aluminum garnet (YAG) was prepared using a facile electrochemical technique. Four samples were synthesized in 0, 20, 40 and 60°C by electrochemical pulse deposition and were then calcined at 1200°C. The effect of synthesis temperature on morphology and structure of YAG was studied using X-ray diffraction, Fourier transform infrared spectroscopy and scanning electron micro...

Polycrystalline Yttrium Aluminum Garnet Fibers from Colloidal Sols

Polycrystalline yttrium aluminum garnet (YAG) fibers were prepared from commercially available colloidal sols of Y,O, and AlOOH and water-soluble polymers. The fibers were dry spun and all processing was performed in air. Transformation to YAG was complete by =1300"C, and the fibers were mostly dense by 1600°C with a final fired diameter of 120 pm. A bend test was used to characterize mechanica...

Bulk optical damage thresholds for doped and undoped, crystalline and ceramic yttrium aluminum garnet.

We measured the bulk optical damage thresholds of pure and Nd-doped ceramic yttrium aluminum garnet (YAG), and of pure, Nd-doped, Cr-doped, and Yb-doped crystalline YAG. We used 9.9 ns, 1064 nm, single-longitudinal mode, TEM00 pulses, to determine that the breakdown thresholds are deterministic, with multiple-pulse thresholds ranging from 1.1 to 2.2 kJ/cm2.
