英文摘要The effect of gel-freezing dry method (-50 degrees c, 8pa) was investigated on drying and dewatering on a yttrium hydroxynitrate precursor. precursor through gel-freezing dry accumulated softly with a clearer card-like figure than that through traditional oven dry. after calcination at 1100 degrees c, the powder through gel-freezing dry method has finger particles, narrower particle distribution and larger surface area than that through oven dry. after dry process, samples were sintered at 1700 degrees c for 4h in vacuum, transparent polycrystalline ceramics were produced with uniform crystallines. the mean size of crystallines is around 40 mu m. relative density of the transparent ceramic reaches 99.6%. after milling and polishing, samples get a high in-line transmittance of 60% at 400nm wavelength, and it also gets a high in-line transmittance ultraviolet wave band, which is similar to single crystalline yttrium oxide.
