WebAn exhaustive characterization of the physicochemical properties of gum arabic (GA)-coated Fe3O4 magnetic nanoparticles was conducted in this work. These nanoparticles were obtained via the in-situ coprecipitation method (a fast single-step method) in two GA:Fe ratios, 10:1 and 20:1, respectively. Several experimental techniques were applied in the … WebBasalt fiber (BF) is a type of high-performance inorganic fibers made from natural basalt by melt spunning at ~ 2700°F (1500°C). Unlike glass fiber production, no additives are added to the melt, which makes BFs environmentally benign besides their noncombustible and explosion-proof properties.
