Particles Spreading Phenomena in the Case of Glass Thermal Spraying
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…
RELEVANCIA DEL FACTOR “MATERIA PRIMA” EN UN PROCESO CERAMICO INDUSTRIAL: UN CASO DE ESTUDIO VENEZOLANO
Frente a los problemas de calidad experimentados en producción por muchas empresas cerámicas venezolanas, una de las respuestas consiste en realizar, en los diversos sectores de las minas proveedoras, un análisis no solamente de…
SMOOTHING IRON OXIDE-BASED GLASS PARTICLES WITH AN OXYACETYLENIC FLAME
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…
STATUS ACTUAL DE LOS REFRACTARIOS EN VENEZUELA:
MATRIZ F-O-D-A Y PERSPECTIVAS FUTURAS
La industria manufacturera de materiales refractarios en Venezuela tiene más de 50 años. Entre las décadas del 60 y del 90, se generaron varias industrias fabricantes de especialidades refractarias y de materias primas electrofundidas para el…
Two Routes for making Glass Ceramic Microspheres
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…

USING SEM FOR COMPARING TRENDS TO FORM CENOSPHERES IN SPRAY DRYING PROCESSES
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…
