助熔剂法生长二钛酸钡单晶
Growth of barium dititanium single crystals by flux method
摘要
Abstract
To overcome the difficulty of growing barium dititanate single crystals due to the narrow temperature range for its thermodynamic stability,we tried and successfully synthesized barium dititanate single crystals by a flux method for the first time. We used barium dititanate powders as precursors,barium metaborate as flux and boron oxide as additives to stabilize the barium dititanate phase. The molar ratio of barium dititanium to barium borate was 2:3, and the molar ratio of barium dititanium to boric oxide was 1:0.25; the soaking temperature was 1 180 ℃; the crystal growth stopped after the temperature decreased slowly to 1 080 ℃ with a cooling rate 3.3 ℃/h. The crystals of 2.5 mm ×0. 3 mm ×0. 3 mm in size were obtained.关键词
