Magnesium oxide crystallites having mean dimensions in the range of 25–1000 A can be prepared by controlled thermal decomposition of the carbonate. Following some earlier investigations of Birks and Friedman, we have determined the mean size and size distribution of several such MgO samples from the broadened X-ray diffraction lines which they exhibit.

As an example, filler alloy 4643 was developed for welding 6xxx series base alloys and developing high mechanical properties in the post-weld heat-treated condition. This alloy was developed by taking the well-known alloy 4043, reducing the silicon, and adding 0.10 to 0.30 percent magnesium, thus ensuring its ability to unquestionably respond to post-weld heat-treatment.
Guanín was an alloy of copper, gold and silver, similar to red gold, used in pre-Coluian central America. The name is borrowed from the Taíno, who prized it for its reddish-purplish color and unique smell, and associated it with both worldly and supernatural power.

We describe a new process for preparing porous solid phase microextraction (SPME) coatings by the sputtering of silicon onto silica fibers. The microstructure of these coatings is a function of the substrate geometry and mean free path of the silicon atoms, and the coating thickness is controlled by the sputtering time. Sputtered silicon structures on silica fibers were treated with piranha

This stability of the Ni3Fe alloy formed in this study is consistent with the higher corrosion resistance of stainless steel doped with nickel and other nickel alloys (Lai, 1990). To further investigate the nature of metal dissolution as a result of pre-calcination, the solubility of nickel and iron from limonite reduced at 500, 600 and 700 8C 8 C are correlated in Figs. 14–16, respectively.
