We, also, attempted to illustrate the relationship between devitrification of the rigid amorphous fraction and crystallization kinetics.
The groundmass was replaced by a granoblastic aggregate of quartz, sericite, and opaque minerals, but it is still possible to recognize ghosts of devitrification textures, such as perlitic, spherulitic and patchy structures or sintaxial growths over the crystals (Fig.
Rehabilitation of the existing windows and exterior elements of the inventory window with a focus on the speed and Schliessbarmachen and the renewal of the seal;- Tight connection of the inventory window inside;- Installation of new window and door elements;- Devitrification and renewal of the inventory window glazing elements and the glazing of the new windows and doors;- Function test of sun protection systems outside inventory and cleaning;- Cleaning of the profiles of the inventory window systems.
Disideologization, devitrification, pluralization of the view of facts is occurring, Mircev comments.
The basaltic rocks are generally fine-grained and porphyritic, with sub-ophitic to ophitic clinopyroxene, while the intersertal glass is charged with ore due possibly to devitrification.
Others include that they may be accretionary lapilli formed in volcanic ash eruptions, impact spherules formed in impact events, or devitrification spherules resulting from formation of crystals from formerly melted material.
Devitrification due to contamination: Oils, salts and other contaminates cause devitrification of the quartz.
The zeolites and associated secondary minerals were sequentially deposited from the outer wall to the centre of amygdales and veins in the basalts (Figure 8) Chemical elements necessary for the formation of these mineral phases were released directly as a result of hydrothermal devitrification.
if there is enough time and the temperature is sufficiently high, devitrification of the layer will take place, resulting in a crystalline phase.
2[degrees]C, the storage modulus went down because of the devitrification of the adhesive.
5[degrees]C and the second at -47,7[degrees]C, represented a crystallization peak of solution, and probably a devitrification due to the presence of ice forms (BAUDOT & BOUTRON, 1998), this could explain the lower survival rates of DF containing solutions trough the thawing process as compared with PROH-EG cryoprotectant solution.
Bentonite is a rock formed of highly colloidal and plastic clays composed mainly of montmorillonite, a clay mineral of the smectite group and is produced by in situ devitrification of volcanic ash.
