First, fine BaTi2O5 powders were made by a sol–
gel method. Ba(OC2H5)2 and Ti[OCH(CH3)2]4 with a molar
ratio of 1 : 2 were mixed in a solution of methanol and
2-methoxyethanol in a glove box with N2 gas flow. The yellow
clear solution obtained was put into a cool-stirrer (CSB-
900 N) and was cooled to 0 ◦C to form a colorless transparent
sol. Then it was sprayed with water for hydrolysis while
being stirred until it became a transparent gel with a high
viscosity. After it was aged at 50 ◦C for 24 h, we obtained
a dark-yellow amorphous precursor which was subsequentlypulverized, ground, and calcined twice, at 650 ◦C for 12 h and
at 1000 ◦Cfor2 h, respectively.As a consequence,white powders
of BaTi2O5 with a size ranging from 20 nm to 200 nm
were obtained.
KF-doped BaTi2O5 ceramics were synthesized by solidstate
reaction of mixed KF (Merck, 99%) and the above
sol–gel-derived BaTi2O5 powders

First, fine BaTi2O5 powders were made by a sol–gel method. Ba(OC2H5)2 and Ti[OCH(CH3)2]4 with a molar ratio of 1 : 2 were mixed in a solution of methanol and 2-methoxyethanol in a glove box with N2 gas flow. 首先用溶胶-凝胶制备微细的BaTi2O5粉末。将摩尔比为1:2的Ba(OC2H5)2 和Ti[OCH(CH3)2]4在甲醇和2甲氧基乙醇的溶液中混合,这在通氮气流的手套操作箱中进行。 The yellow clear solution obtained was put into a cool-stirrer (CSB-900 N) and was cooled to 0 ◦C to form a colorless transparent sol. 将得到的黄色清澈的溶液放进一个冷却搅拌器(CSB-900N)中,并冷却到0℃,从而形成一种无色透明的溶胶。Then it was sprayed with water for hydrolysis while being stirred until it became a transparent gel with a high viscosity. 然后将溶胶用水喷淋进行水解,同时进行搅拌,直至溶胶变成高粘度的透明凝胶为止。After it was aged at 50 ◦C for 24 h, we obtained a dark-yellow amorphous precursor which was subsequently pulverized, ground, and calcined twice, at 650 ◦C for 12 h andat 1000 ◦Cfor2 h, respectively. 在经过50℃下24h的老化后,我们就得到了一种暗黄色的无定形前驱体,它随后被粉碎、研磨和煅烧两次,分别在650℃下煅烧12h,和在1000℃下煅烧2h。As a conseque
