Dicalcium phosphate dihydrate (DCPD), Ca[HPO.sub.4]*2[H.sub.2]O, occurs as the mineral brushite and crystallizes
in the monocinic space group Ia with unit cell parameters a = 5.812(2) [Angstrom], b = 15.180(3) [Angstrom], c = 6.239(2) [Angstrom] and [beta] = 116.42(3)[degrees], Z = 4 (41).
at substantially lower temperatures than PET-200 to 220 F vs.
In any case, the XRD results have shown that the PVDF phase in the PVDF/PET-based composite could crystallize
into [alpha]-phase easily; however, the crystallization of the PET phase was inhibited on a large scale because of the presence of CB/GR additives and the rigidity of PET molecular chains.
to build deep-sea vents along the ridge.
While all rubbers become glass-like at a sufficiently low temperature, only certain rubbers crystallize
If bottle-grade PET did crystallize
it would become cloudy and, more importantly, it would lose its impact resistance.
Nylon 11 11 crystallizes
from 1, 4-butanediol as the elongated and multilayered lath-shaped crystalline lamellae (Fig.
These units will help make CPET more widely available in place of standard amorphous PET and may push recyclers to crystallize
PET flake for customers.
To do so, they created novel alloy compositions that don't crystallize
as readily as simpler blends do.
In contrast, when crystallized from dilute solution, nylon 12 14 crystallize
Into very ordered [alpha] and [beta] phase crystals and no reflection at 0.42 nm can be observed at room temperature.
As the cloud cools, carbon blasted from either graphite or limestone on the ground can crystallize
to form diamonds.
For the success of this process, it is important that polymers crystallize
rapidly so that the crystallization is complete.
