Abstract

The effect of gel-freezing dry method (--50℃, 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℃, the powder through gel-freezing dry method has finer particles, narrower particle distribution and larger surface area than that through oven dry. After dry process, samples were sintered at 1700℃ for 4h in vacuum, transparent polycrystalline ceramics were produced with uniform rystallines. The mean size of crystallines is around 40μm. Relative density of the transparent ceramic eaches 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.

Key words： transparent ceramics; yttria powder; gel-freezing dry
