Abstract

Cobalt precipitation tube synthesized through “silica garden” route was characterized using a number of analytical techniques. One of the prominent phases was identified as hydrated β-Co2SiO4. Particle clusters with diameter smaller than 40 nm could be observed. Chemical composition of the exterior and interior wall of the tube was remarkably different with distinct concentration gradient for O, Na, Si, Cl and Co. Synthesized tube was weakly magnetic with low retentivity and coercivity. Chemical analyses confirmed presence of non stoichiometric compositions. Cobalt precipitation tube was hygroscopic and contained both physically and chemically bound moisture.
