Influence of milling parameters on particle size of ulexite material
(Elsevier Science BV, 2016)Commercial raw ulexite (U) materials were milled from 0 h to 8 h by using mechanical milling technique for var-ious initial powder size (−3mm;−75μm), ball to powder ratio (5:1; 10:1), and ball size (10 mm; 5 mm). Par-ticle ... -
An investigation of magnetoresistivity properties of an Y3Ba5Cu8Oy bulk superconductor
(Elsevier Science BV, 2015)A bulk ceramic superconducting sample was fabricated using the standard solid state reaction (SSR) method in the stoichiometric ratio of Y:Ba:Cu:O (3:5:8). The electrical and microstructural properties of the sample were ... -
