1. The preparation technique for cobaltous aluminate, the coating process on mold wall and casting process are also introduced.

2. The company main product is the high pure cobaltous chloride, the cobaltous sulfate, the cobaltous carbonate, the cobalt blue and so on.

3. The preparation technique for cobaltous aluminate,(http://) the coating mold wall and casting process are also introduced.

4. Due to somewhat higher chloride in cobaltous carbonate prepared by cobaltous chloride and sodium carbonate, its application is limited.

5. However, cobaltous acetate of relatively high concentration in sol-gel coatings might undermine both the stability and the corrosion resistance performance of the coatings after immersion.

6. A standard volumetry for determination of cobalt in cobaltous oxalate was studied and improved.

7. At the same time, double carbonylational catalysis ability of the catalysis systems which are composed of the other ligands and cobaltous chloride is researched.

8. A series of cobalt platinum tungsten alloys were deposited with sodium tungstate and cobaltous sulfate as the main salts and citrate as the complex agent.

9. This standard solution was accurately prepared in super-clean laboratory with potassium chloropatinate-crystallized cobaltous chloride and sub-packed in 20 ml ampoules.

10. The aim of this study is to investigate the effect of cobaltous acetate doping on the corrosion resistance of sol-gel coatings on aluminium alloy LY12.

11. Anthraquinone is prepared by the liquid phase oxidation of anthracene with oxygen in the presence of cobaltous salt, manganous salt and bromide.
