Laser was used as a rapid heating and vitrifying way to yield high Fe bearing glasses for biomedical applications. The high amount of Fe2O3 (40-80%), which is an intermediary (instead of a glass forming) oxide, implies a
difficult formation of…

Las granallas de alúmina son más costosas y duran menos que las granallas metálicas, a la hora de preparar sustratos para recubrirlos industrialmente por HVOF. En el presente trabajo, se reemplaza alúmina por acero como…

Zirconia is evermore in demand as a thermal barrier coatings (TBC) for energy economy and metal protection. Several methods are in use to produce the coatings, including sol-gel, CVD and PVD, however plasma ablation, has not been notoriously…

Slags may be flame sprayed to produce hollow vitreous or semi-crystalline microspheres.
Feedstock compositions, as well as the heating and cooling kinetics, determine the properties
of the final product. These kinetics were estimated by finite…

Glass ceramics were obtained by annealing of the SiO2–CaO–Fe2O3 system, and the devitrifying effect of adding TiO2 was compared with Fe2O3. In spite of its higher field strength, TiO2 was unable to accelerate the devitrifying kinetics as…

El presente documento tiene por objeto:
a) Estudiar aspectos endógenos de los retos y dificultades que enfrentan las alfarerías industriales venezolanas.
b) Identificar sus fortalezas y relacionarlas con su desempeño en términos de…

En el presente trabajo se estudia la viabilidad de aplicar leyes lineales de mezcla en composiciones arcillosas que incluyan ilitas, pirofilita, caolinita y desgrasantes, con respecto a diversas propiedades como la plasticidad, el comportamiento al…

Glasses in the Fe2O3–SiO2–CaO system are potential candidates for many technological applications due to their ferrimagnetic and semiconductive properties, which have been extensively studied; in this sense, the effect of adding different…
