在合适的乙醇—氨化PAA介质中合成超微细碳酸锰前驱体,将前驱体在含氧气氛中先于450℃保温30-45min,再升温至980-1100℃并保温45min,获得高纯超细Mn3O4粉体,通过多种方法进行表征,结果显示其纯度达到99.3％,比表面积达15.6m2/g,晶体粒径＜2um.
This study evaluated high water absorbency and constantly phosphorus release properties of two novel hybrid hydrogel materials as potential hydrogel fertilizers.In this article, the hybrid hydrogel ma
Besides the qualified spectral properties, the commercial phosphors require other qualities such as high luminescent intensity, good powder mobility, well-shaped crystal form and uniform size distribu
Cystinosis and some other diseases are characterized by high concentrations of cystine in urine (usually ＞400 mg L-1).Until now many methods have been developed to detect cystine in human urine, such
有机化学反应通常在反应釜中进行，由于化学物质的粘稠吸附性，使得反应釜中化学物质粘壁成为妨碍正常生产的一个重要问题，本文通过溶胶-凝胶法制备具有低表面能的纳米溶胶，将其喷涂在洁净不锈钢反应釜内外壁，经350℃固化后，能在不锈钢涂料反应釜壁上形成厚度为微米级的不粘涂层。通过在制作涂料的不锈钢反应釜的试验表明，此方法制备的涂层施工工艺和固化工艺简单，防粘效果持久性强，具有良好的应用前景。
In this paper, ordered crystal mesoporous γ-Al2O3 was synthesized by one-step method and it was used to study the adsorption capacity of fluoride in drinking water.A system studies about the adsorptio
Ordered mesoporous alumina (OMA) was synthesized through facile sol-gel method.Adsorption ability of the OMA is evaluated by choosing the methylene blue as an adsorbate,and this material exhibited ext
Two kinds of crystalline and mesoporous alumina samples were prepared using aluminium isopropoxide as precursor and P 123 as template agent.They are labeled OMA-800 and OMA-400 in this paper, and test
LSGM (La0.9Sr0.1Ga0.8Mg0.2O2.85)是目前最有前景的固体氧化物燃料电池(SOFC)电解质之一.然而LSGM中常伴有高阻的第二相,影响其性能,而制备单相的LSGM粉体一直是一个难题.本研究分别采用固相一步法、固相两步法、熔盐法以及溶胶凝胶法制备了LSGM粉体,并采用X射线術射仪、X射线光电子能谱分析仪对材料的相组成以及体系中元素电子价态进行了分析.结果显示固相两步法较固相
The synthesis of various gel-type electrolytes is completed in different experiments of this study.The experiments of the study use LiI and I2, to serve as electrolytes, which are added with high-mole
