The effects of the milling time on the fabrication of transparent polycrystalline yttrium aluminum garnet YAG ceramics were investigated by slip casting and vacuum sintering. The results showed that the best milling time for the deagglomeration of the powder mixture was 16 hours and the slurry prepared during this time showed a near

Tape casting process was used to produce Al2O3 substrates in an aqueous system with acrylic latex emulsion as binder. The present work studied the slurry formulations in aqueous medium of Al2O3 powders with different particle sie distribution and made correlation to the green and sintered tapes. Two commercial alumina powders one sub

High thermal conductivity aluminum nitride AlN substrates were prepared by aqueous tape casting. The characteristics of surfacetreated AlN powder were studied in aqueous ballmilling media. The oxygen content of AlN powder with the dispersant was lower than that of AlN powder without the dispersant at the same ballmilling time

A precursor tape casting method is one in which chemical precursors are converted into a final chemical phase from green tapes to products. Because chemical precursors are employed rather than the final powder materials sintering is not required to form the material. Lower annealing temperatures instead of high temperature sintering allow the formation of grains of about 1 to about 100
