1. The clays consist of silica tetrahedra and the octahedra contain magnesia surrounded by oxygen atoms and hydroxyl groups.

2. In a similar way, sheets of octahedra are formed from aluminium, oxygen and hydroxyl groups.

3. Making oars. First step - from square to octahedron.

4. The octahedron steel ingot and V - anvil forging bar can effectively prevent cracks in crystal boundary.

5. The synthesis of regular octahedron cobalt oxide battery material in supercritical carbon dioxide system was studied.

6. The mononuclear complex 10 is octahedron structure with Zn(II) being coordination center.

7. An octahedral tessellation approximates a spherewith an octahedron whose vertices are all on the unIt'sphere.

8. Companies are mainly engaged in the SS 1 - SS 40 # octahedron,() ten surface drilling a variety of colors.

9. The cycle sum of the rotation group of the octahedron was calculated.

10. The particles of the spinel oxides prepared in microwave field have very regular octahedron or polyhedron crystal morphology with well crystallization.
