1·The method overcomes the shortcoming of grain growing above the initial crystallization temperature in annealing method, successfully preparing nano-crystalline material of very small grain .
该方法避免了传统的退火法在晶化温度以上晶粒长大这一缺点,成功制备出晶粒极细小的纳米材料。
2·The study indicates that synthetic conditions such as crystallization temperature and time, the type and composition of organic templates, could effect on SAPO-11 molecular sieves synthesis greatly.
研究表明,合成条件,如晶化温度和时间、有机模板剂的类型和组成等,都对SAPO - 11分子筛的合成有很大影响。
3·The process of in-situ crystallization is that the roasted microparticles in the liquid phase convert into sodium silicoaluminate gel first and then the gels convert into zeolite Y gradually.
原位晶化过程是焙烧微球在液相组分中先转变为硅铝酸钠凝胶,随后硅铝酸钠凝胶逐步地转变为Y型沸石。
4·The GPE made of PVDF has bad solution retention capacity because of crystallization of PVDF and its heat stability has improved after adding PMMA.
由PVDF形成的凝胶电解质由于不断晶化,导致对电解液的保持能力欠佳,用添加pmma的方法改善了其热稳定性。
5·The technology has advantages that decrease the cost of production, shorten the crystallization period, and simplify synthesis process.
此工艺具有生产成本低,晶化时间短、过程简单等特点,是有工业应用前景的生产方法。
