The ancient Indo-Aryans were so highly skilled in complex metallurgic techniques, they created this pillar which seems to never rust. This unique masterpiece was created in honor of God Vishnu – The Lord Protector!
The FTIR spectrum proved the presence of g-FeOOH, a-FeOOH and d-FeOOH. The d-FeOOH was the major component of the rust as the peak was of relatively larger height compared to the others. An interesting result from the FTIR spectrum was that there was a distinct signal from the phase FePO4. 2H2O and the shoulder from this phase was also identifiable. Therefore, the results of the FTIR study indicated that the constituents of the scale were g, a and d-FeOOH, in addition to a small amount of FePO4. In order to further understand the nature of the rust, the Mössbauer spectrum obtained from the rust in the transmission mode was analysed. The presence of g-FeOOH, a-FeOOH and d-FeOOH in superparamagnetic form was confirmed. The very fine particle size of these oxyhydroxides was also confirmed. The presence of iron phosphate was also confirmed. Finally, the rust was also composed of magnetite that was incorporated with some ions.
In the Dacian sanctuary of Racoş some Dacian un-oxidizing iron nails were found. Tested with X rays, it was discovered that, indeed, the nails were 2,000 year old. In their constituency they have pure iron (99.97%), magnetite, iron oxide and aluminum silicates. The nail does not rust. In the world there are two other samples of un-oxidizing iron: the iron pole in Delhi and the disc in Mongolia, studied by N.A.S.A. Large bars of Dacian iron were found, over 40 kg, although, in those times, not even the Romans could melt in their furnaces, bars larger than 25 kg.
The Roentgenograma performed on the extra-pure Dacian iron (1-Fe of 99.97% purity). No traces of cementite are visible which means the iron was not obtained in a reduction with C. Its surface was protected against rust with three layers: magnetite, iron oxid and alumosilicates (according to research made by ICIDAC), director A. Vartic, at the specialized institutes of The Academy of Science in The Republic of Moldavia, under the academician Sergiu Rădăuţanu. Among the team of researchers were Dr. Constantin Posteuca, Dr. Ion Andronic, Dr. Gh. Kiosse, Dr. Galina Volodin, Dr. Daria Grabco and Dr. N. Malcoci.
