Synthesis and characterization of magnetic nanoparticles coated with silica through a sol-gel approach Síntese e caracterização de nanopartículas magnéticas revestidas com sílica através de um processo sol-gel
This paper investigates the influence of reaction medium pH on silica-coating of magnetite nanoparticles. Magnetite nanoparticles were prepared by means of a reduction-precipitation method using ferric chloride as a starting material, which was partially reduced to ferrous salts by Na2SO3 before alk...
