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…

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…

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…

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…

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…

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…

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…

ABSTRACT :
A simple thickness measurement method is proposed for non consolidated, friable thick coatings
(1-100 μm), marking a furrow in the coating and observing with an optical microscope. Its low field depth
is used in association with the…
