The test and analysis of the exchange current density of the carbon nanotube and perovskite compound oxygen electrodes;

A brief review on perovskite-type and perovskite-like complexoxides widely applied in catalysis,sensor, superconductor, ferroelectronic ceramies and other functional materials is given,and the problem remained and the develop-ment of these mixed oxides are also studied.

The catalytic behaviour of perovskite type muhiple oxide LaMnyCo1-yO3 for CO oxidation and the relationship between the catalytic property and solid state physicochemical properties of the catalysts are discussed, and the main factors influencing the catalytic atcivity are also discussed from the point of view of compensative relation between the activation energy and pre-exponential factor.

Study on zirconolite and titanite synrocsolidification of uranium;

The solid-state reaction synthesis and sintering of zirconolite and sphene were researched by thermogravimet- ric-differential scanning calorimetry (TG-DSC) analysis and X-ray diffraction (XRD) analysis.

The paper deal with synthesis of zirconolite based synroc.

Radioactive nuclides are solidified at crystal lattice as one part of crystalloid by zirconolite-rich synroc, which greatly enhances the long-term safety of radioactive waste disposing.
