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…
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…
In this study, different frit compositions were prepared in the SiO2–CaO–Fe2O3 system. The amounts of Fe2O3 were varied between 10 mass-% and 40 mass-%. The frits were melted and characterized using several different techniques in order…
The cavitation-erosion resistance of tetragonal zirconia polycrystals with 3 mol% Y2O3 (3Y-TZPs) has been studied in specimens sintered in the temperature range from 1500 to 1590 ºC. The study presents mass loss measurements after exposure to…
