Synthesis and reaction behavior of calcium silicate hydrate in basic system LIU Gui-hua(刘桂华), HE Qiang(贺 强), LI Xiao-bin(李小斌), PENG Zhi-hong(彭志宏), ZHOU Qiu-sheng(周秋生) (School... of reaction time. The decomposition rate is all less than 1.2% in caustic solution, and XRD pattern of the residue after reaction with caustic solution is found as the same as that of original calcium silicate......
principle of preparation of Cr3C2 and Cr with Cr2O3 and C as raw materials, and found that there are two principles for Cr2O3 reduced by carbothermal method, one reaction depends mainly on CO/CO2 gas-solid transmitted and another one depends mainly on the solid-solid reaction between carbon and chromium oxide. The latter is dominant when Cr2O3 and C contact closely. LI et al [14] found......

, suggesting that a portion of the Mg phase was hydrided to MgH2 by the mechanically driven solid-gas reaction Mg+H2→MgH2. With the increase of the milling time, the fraction of MgH2 phase increased while... accelerated, attributing to the initiation of the Mg hydriding reaction, that is, the transition of Mg(H) solid solution (α phase) to MgH2 (β phase), with the mechanical energy transferred by the ball......
