چکیده
This study investigated the thermophysical, physicochemical, and electrical characteristics of electrode coatings developed for application in weld joint nuclear power plants (NPPs). The extreme vertices design technique has been used this work to develop Al2O3-SiO2-CaO-Na3AlF6-based Shielded metal arc welding (SMAW) electrodes. Twenty-six coating compositions were formulated, flux milled into a fine powder further characterization. X-ray diffraction (XRD) was utilized investigate structure phases composition, Fourier transform infrared (FTIR) analysis employed determine nature bonds. coating's thermal characteristics, including conductivity, diffusivity, specific heat, evaluated using hot disk equipment. Enthalpy change stability determined Differential analysis(DTA)/ differential scanning calorimetry (DSC) technique.. precision inductance (L), capacitance (C), resistance (R) (LCR) instrument examine coatings. In addition, regression model each property statistical correlation between properties mineral interactions. Results reveal that individual elements their binary tertiary interaction significantly influence

Measuring and Modeling Viscosity of CaO-Al2O3-SiO2(-K2O) Melt
The effect of K2O on viscosity in CaO-SiO2-Al2O3 melt has been measured by a rotating spindle viscometer. It is indicated from the experimental results that viscosity first increases then decreases with the increasing content of K2O; the maximum viscosity occurs in the field of K2O/ Al2O3 > 1. After gradually adding K2O, the transformation of bridging oxygen (from being bonded with Al ion charg...
متن کاملSynthesis of Nanoscale CaO-Al2O3-SiO2-H2O and Na2O-Al2O3-SiO2-H2O Using the Hydrothermal Method and Their Characterization
C-A-S-H (CaO-Al₂O₃-SiO₂-H₂O) and N-A-S-H (Na₂O-Al₂O₃-SiO₂-H₂O) have a wide range of chemical compositions and structures and are difficult to separate from alkali-activated materials. Therefore, it is difficult to analyze their microscopic properties directly. This paper reports research on the synthesis of C-A-S-H and N-A-S-H particles with an average particle size smaller than 300 nm by apply...
متن کاملdesulfurization of plain carbon steel by cao-al2o3-sio2 and cao-al2o3-sio2-x (x = na2o, sro) synthetic slags
synthetic slag process decreases sulfur and phosphorus contents of steel, improves inclusion removal, protects steel from atmosphere and prevents temperature drop of the liquid steel in the ladle. in this study, the synthetic slags of ternary cao-al2o3-sio2,and quaternary cao-al2o3-sio2-na2o and cao-al2o3-sio2-sro systems were pre-melted and then were kept in contact with the liquid steel in a ...
