Recently Progress in Preparation Technology of Inorganic Hollow Microspheres;

This paper systematically highlights solid-template methods preparing hollow inorganic spheres based on colloid or capsule template, and sets forth the different principles of forming shell in homogeneous or inhomogeneous mother solution, summarizes the involved applications and the hot headway.

Large scale preparation and characterization of NiO hollow microspheres

NiS2 hollow microspheres were prepared by hydrothermal reaction between NiCl2·6H2O and Na2S2O3·5H2O at the low temperature of 150°C.

Subsequently, the similar microstructured NiO hollow microspheres were obtained by calcining the above precursor at 400 ℃ for 2 h.

Non-close-packed photonic crystal of TiO_2 hollow spheres:Fabrication and photonic bandgap calculation;

The relations of the effective moduli of the composite,the thickness of the hollow sphere wall,volume fraction of the filler,and thickness of the coating were investigated.

Density matched microencapsulation technique has been developed for production of high quality hollow polymer microshells employed in inertial confinement fusion(ICF) experiments.

The progress of production of polymer microshells for inertial confinement fusion experiments in recent years is summarized.

　Concentricity, sphericity of microshells prepared by the technique was typically　more than 98%, 99% respectively.
