The surface morphology,mean diameter,shell thickness and structure of hollow silica microspheres under different reaction time,temperature,stirring speed and content of hydrochloric acid were examined and determined by employing SEM,XRD,FTIR,BET and TG methods.

Monodispersed CdS/SiO2 core-shell nanoparticle composites and hollow SiO2 spheres with 30~50nm were been synthesized in W/O microemulsion containing Triton X-100,cyclohexane and n-caprylic alcohol.

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.

With PSA as a template, ZrO_(2) hollow spheres composed of tiny crystalloid which was 17 nm in size were successfully prepared by coating directly on PSA.

Hollow spheres as new advanced functional materials are becoming one focused research field, principally because of their novel properties, such as low density, high specific surface areas and infiltration ability.
