Sol–gel process

18 · In materials science, the sol–gel process is a method for producing solid materials from small molecules. The method is used for the fabrication of metal oxides, especially the oxides of silicon (Si) and titanium (Ti). The process involves conversion of monomers into a colloidal solution that acts as the precursor for an integrated network (or gel) of either discrete particles or network ...

Uranium

26 · Uranium is a chemical element with the symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table.A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons.Uranium is weakly radioactive because all isotopes of uranium are unstable; the half-lives of its naturally occurring isotopes range between 159,200 years and 4.5 billion …

Mechanical Milling

R.W. Cahn, in Encyclopedia of Materials: Science and Technology, 2001. Mechanical milling is a direct descendant of the technique of mechanical alloying, invented in the late 1960s by Benjamin (1970); this is a method involving the ball-milling of constituent powders to create an industrial alloy which is precipitation-hardened and may also be hardened by an oxide dispersion.

high-energy ball milling

A.S. Edelstein, in Encyclopedia of Materials: Science and Technology, 2001. 1.4 Mechanical Synthesis Methods. High-energy ball milling, also called mechanical attrition, can be used to reduce the grain size of materials from many micrometers to 2–20nm (see Mechanical Alloying).This is a result of the cold-working process creating large-angle grain boundaries.
