采用快速碱介导溶胶-凝胶法制备了纳米生物活性玻璃。凝胶化时间约为2 min。通过添加氨水溶液可以控制生物活性玻璃的尺寸。TEM图像显示，使用IM氨溶液，NBG颗粒尺寸为20-40 nm。TG-DSC曲线表明，有机和无机前驱体在550 ℃之前已经完全分解。在空气中600 ℃煅烧的NBG的WAXRD图谱证实煅烧玻璃一般以非晶态存在。(c)2006 Elsevier B. V.保留所有权利。
Nano-bioactive-glasses have been prepared by a quick alkali-mediated sol-gel method. The gelation time was around 2 min. The size of bioactive glasses could be controlled via addition of ammonia solution. The TEM images showed that the NBG particles size were 20-40 nm using 1 M ammonia solutions. TG-DSC curves indicated that the organic and inorganic precursors have been decomposed completely before 550 degrees C. WAXRD pattern of NBG calcined at 600 degrees C in air confirmed that the calcined glass generally existed in amorphous state. (c) 2006 Elsevier B.V. All rights reserved.
