The purpose of a "'mineralizer "'is to facilitate the transport of insoluble nutrient to a seed crystal by means of a reversible chemical reaction.
42.
Because the substrate acts as a seed crystal, the deposited film may lock into one or more crystallographic orientations with respect to the substrate crystal.
43.
Also, it is important that the silicon-containing nutrient be kept away from the other ingredients to prevent nucleation and confine growth to the seed crystals.
44.
Since a huge number of minuscule seed crystals are present, a nearly equal number of crystallites result, and the size of any one grain is limited.
45.
Bradley clearly sees Crystal City, a town of 4, 000 about 30 miles south of St . Louis, as his version of such Norman Rockwell settings.
46.
The methods involve heating polycrystalline material above its melting point and slowly cooling it from one end of its container, where a seed crystal is located.
47.
During the growth process, a seed crystal is slowly pulled from a bath of molten semiconductor, which then grows into a rod-shaped crystal ( hermetically sealed can.
48.
You'll walk inside a crystal dome, see crystal works by such artists as Salvador Dali and see a theaterlike display of crystals that appear to be a galaxy.
49.
After speaking with Jeffrey Anzaldi, his brother-in-law Dan Martin said Tuesday that " we are very unhappy and disgusted " at Gierbolini's release and her desire to see Crystal.
50.
The seed crystal acts as a site of nucleation; the temperature is kept steady at a point where the surface of the mixture is just below the melting point.
