J. Cent. South Univ. (2018) 25: 795-804 DOI: https://doi.org/10.1007/s11771-018-3784-x Effect of magnetite content on Bond work index and preconditioning:Case study on Chadormalu iron ore mine... by detonation cord. The results showed that with higher percentage of magnetite, the number of fractures induced by blasting increased. Bond work index and magnetite percent were investigated......
into the liquid filler under ultrasonic action and a bond with homogeneously distributed reinforcements was obtained after solidification. The volume fraction of SiC particles in the bonds could be varied by changing the brazing temperature. The maximum SiC particle volume fraction of the bond material reached 37% at a brazing temperature of 500 ℃. The shear strength of the brazed bonds......

) Abstract: The SiO2 nanoparticles prepared by the hydrolyzing tetraethylorthosilicate were directly coated with CeO2 by chemical precipitation technique. The as-prepared samples were analyzed with X-ray... a significant shift toward pure CeO2. The shell CeO2 is chemically bounded with SiO2 core, and the Si-O-Ce bond forms between them. The surface roughness within 2 μm×2 μm area of thermal oxide film......
