Mosavian, Seyed Yousef; Ebrahimi-Kahrizsangi, Reza; Khah, Mohammad Malakooti; Hamidi, Zeinab; Rafiei, Amin; Behzadi, Mohsen published the artcile< Effect of Mechanical Activation on the Kinetics of Silica Carbothermal Reduction in non-Isothermal Conditions>, Application of C4H2Br2N2, the main research area is silica carbothermal reduction non isothermal condition mech activation kinetics.
The effect of mech. activation on the synthesis temperature decreasing of silicon carbide was investigated and a kinetic model of a carbothermic reduction of silicon carbide was obtained. Silicon carbide was synthesized using silica activated in a planetary mill at different times up to 40 h under an argon atm. Structural changes due to the milling and the reduction of the activated silica were studied by the X-Ray diffraction (XRD) method and non-isothermal TGA with a heating rate of 10oC min-1 resp. The kinetic model obtained by the fitting technique for an unmilled sample was found to be chem. controlled of the second order with E = 138.92 Kcal.mol-1 and A =3.92×1015 s-1. For the sample milled up to 20 h, according to the Avrami-Erofeev3 equation; A = 1465633 s-1 and E = 66.71 Kcal.mol-1.
Silicon published new progress about Activation energy. 3921-01-5 belongs to class pyrimidines, and the molecular formula is C4H2Br2N2, Application of C4H2Br2N2.
