and their activation energy values indicated that creep was accommodated by grain boundary sliding through viscous flow of the calcium silicate grain-boundary phase. Two brands exhibited dramatic time-hardening behavior which resulted in their creep not being well-represented by the power-law creep form...
通过运用FactSage中的Viscosity模块与PhaseDiagram模块进行计算,与实验测定的炉渣黏度进行对比。结果表明:在10%FeO-CaO-SiO2-MgO-15%Al2O3五元渣系中,MgO含量为12%时,炉渣黏度达到最低;在10%FeO-CaO-SiO2-10%MgO-Al2O3五元渣系中Al2O3的含量为12%时,炉渣黏度最低;当MgO/Al2O3在0.7~0.8之间,炉渣流动性...
The phase diagram of the CaO–SiO2–ZrO2-7 mass% MgO system at 1873 K is initially calculated and shown in Fig. 1. It is noticed that the solubility of zirconia (ZrO2) in the liquid slag phase is relatively small, viz. about 2–3 mass% and the calcium zirconate (CaZrO3) phase is ...
1 of the drawing, lines of invariant refractive index (isofracts) in the high-silica region of the MgO--Al2 O3 --SiO2 system form a series of parallel lines nearly perpendicular to the MgO--SiO2 join of the diagram. These isofracts, corresponding to refractive index values (nD) between...
