- n. The condition of being crystalline
- n. The degree to which a material (e.g. a polymer or a rock) is crystalline
from The Century Dictionary and Cyclopedia
- n. The character or state of being crystalline; crystalline structure.
- n. In petrography, the degree of crystallization in a rock, as compared with the state of glassiness, whether completely or partly crystallized.
The reinforcement can either be an added material, such as metal or ceramic fibers, or internally created by precipitating ductile dendrites within the BMG, yielding partial crystallinity.
Sandalwood and frankincense in the base enhance both the fresh-green-dry and the creamy-ripe-languid sides of the rose, its fragile crystallinity and its heady intensity.
The pattern of crystallinity, however, is far from straight.
"So the question we addressed is 'how does crystallinity propagate through the amorphous mineral?'"
Temperature of dissociation: - The temperatures at which CO2 dissociates from limestone depends on the proportionate amounts of MgCO3 and CaCO3, and on the crystallinity of the stone.
However, a small amount of additive (such as another wax) destroys the crystallinity and could be a way to overcome this limitation.
Because of its crystallinity, jojoba wax appears unsatisfactory as a mold-release agent or as a plug for making molded objects; as the molten wax cools and solidifies it develops too many fracture lines.
For lime production purposes there are two factors related to limestones crystallinity and crystal structure which are of specifc interest:
Where crystallinity is a disadvantage, jojoba wax can easily be made amorphous by adulterating it with small amounts of other waxes.
Hot alkali removes a larger portion of the lignin as well as the hemicellulose (Biochemical Engineering Research Centre [BERC], Indian Institute of Technology, Delhi, unpublished data), but such a treatment appears to increase the crystallinity of the cellulose (19).
