Abstract
붕소와 실리콘으로 이루어진 보로실리케이트의 합성과정과 합성된 보로실리케이트의 조성, 산성도 및 흡착특성을 조사하였다. 합성속도는 온도와 Na2O 농도를 높여주면 빨라졌으나, 그 증진요인은 조건에 따라 달랐다. 합성과정은 용해된 반응물이 핵심이나 결정의 표면에 반응하여 결정이 성장되는 용액전달기구로 모사될 수 있었다. 암모니아와 프로필렌의 승온 탈착실험, 프로필렌과 프로판의 흡착 등온선으로부터 합성된 보로실레케이트의 흡착특성을 고찰하였다.

The synthesis of borosilicate consisted of boron and silicon was stadied. The composition, acidity and adsorption characteristics of synthesized borosilicate were examined. The synthesis rate increased with temperature and concentration of Na2O, but the enhansing effects were different according to the reaction conditons. The synthesis process could be simulated by solution transfer mechanism assuming that crystals grow on the surface of crystal or nuclei with dissolved reactant. Adsorption characteristics of synthesized borosilicate was discussed with temperature programmed desorption patterns of ammonia and propylene and adsorption isotherms of propylene and propane.
