以常规原料为原料，采用两段烧结法制备了掺la的0.75Pb(Mg 1/3 Nb 2/3) o3 -0.25 pbtio3高透明陶瓷。该陶瓷在红外波段的透明度高达65%。得到了较大的二次电光系数66 × 10 -16 (m/v) 2，这是迄今为止在Pb(Mg 1/3 Nb 2/3) o3 - pbtio3陶瓷中报道的最高值。研究了产生阈值电场的铁电相和透明陶瓷的畴结构。
Highly transparent ceramics of La-doped 0.75Pb(Mg 1/3 Nb 2/3 ) O 3 -0.25PbTiO 3 were fabricated by a two-stage sintering method from conventional raw materials. The ceramics exhibited a transparency as high as 65% for the infrared wavelength. Large quadratic electro-optic coefficient of 66 x 10 -16 (m/v) 2 was obtained, which was the highest value reported so far in Pb(Mg 1/3 Nb 2/3 )O 3 -PbTiO 3 ceramics. The ferroelectric phase inducing the threshold electric field E th and the domain structure of the transparent ceramics were studied.
