Table 3　A result of elemental analysis by energy dispersive X-ray analysis (3)

　　　　　　

　Here, hydrogen atom does not measured by EDS. Capable compounds are iron carbide, iron oxide, carbon dioxide, and water. The main constituent of the floating material is iron. More than 50% of atoms are iron. It is considered that the material includes iron carbide. The iron carbide is intermediate chemicals. The ratio among iron atoms and carbon atoms is not fixed. Molecule of iron carbide possesses a polarity and it is able to form a thin membrane.

Summary
It is the result of analyses that iron carbide was produced by oxidation of iron atom in carbonated water. The organometallic molecule of iron carbide forms a membrane in the carbonated water.

-Additional descriptions for the summary-
The iron carbide was investigated to assist Fischer-Tropsch reactions for synthesizing hydrocarbon. It is considered that, the black particle is made of iron carbides. The yellow membrane of transparency was made by synthesizing reaction of iron carbide and water as shown in the picture.
