hydrate, which indicates the stable existence of calcium silicate hydrate in caustic solution. When reacted with soda solution, the decomposition rate increases with the increasing soda concentration.... So the synthesis temperature and soda concentration should be controlled in the process of transformation of sodium aluminosilicate hydrate into calcium silicate hydrate. Key words: calcium silicate......

Spectroscopic investigations and luminescence spectra of Sm3+ doped soda lime silicate glassesY.K.Sharma1,S.S.L.Surana2,R.K.Singh1摘 要:Sm3+ doped soda lime silicate glasses co-doped with As2O3 were prepared and characterised by measuring their absorption spectra in UV-VIS/ NIR regions and luminescence spectra in the visible region. Judd-Ofelt intensity......
Extraction of vanadium from high calcium vanadium slag using direct roasting and soda leachingXin-sheng Li and Bing Xie College of Materials Science and Engineering, Chongqing University, Chongqing 400044, China摘 要:The extraction of vanadium from high calcium vanadium slag was attempted by direct roasting and soda leaching. The oxidation process......
