microsphere2.pdf
Milled particles from a (SiO2-CaO-Fe2O3) glass were smoothed by flame spraying, focusing on the elimination of superficial roughness or angularity without reaching complete fusion of the glass. The purpose of this study is the further application to…

11666_2008_9211_JTST 2008.pdf
The spreading phenomena of particles during thermal spraying are quite difficult to observe given the kinetics of the process. In this work, the splat formation of glass and alumina is theoretically compared, showing that glass transition and…

granallado.pdf
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…

Poster 2 routes glass ceramics microspheres.pdf
Semicrystalline microspheres are generally easily obtained from petrurgical processes, ie crystallization from a melted composition when cooling velocity and oxide compositions are unable to yield total vitrification. However,
when glass ceramics…

cenospheres.pdf
Cenosphere formation is a current phenomenon when spray drying suspensions. An impervious crust is formed as the surface of sprayed droplets is dried by the hot gas, and the residual water inside the droplet is overheated, and breaks part of the…

Poirier Quercia ceramics international last draft.pdf
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…

optimizacion.pdf
Cuando el objetivo de una empresa cerámica es alcanzar una mayor producción, sin invertir en nuevos equipos, su principal preocupación es la optimización del rendimiento de producción de la maquinaria disponible. En…

Poster laser fusion vidrio Fe2O3.pdf
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…
