Los cerámicos basados en silicio, tales como SiC y Si3N4, son prometedores candidatos como material estructural para aplicaciones a muy alta temperatura (>1200ºC) debido a su alto punto de fusión, su excelente estabilidad termomecánica y su baja densidad. Su aplicación por ejemplo en componentes críticos de las turbinas de gas para generación...

Porous graphitic carbons were successfully obtained from wood precursors through pyrolysis using a transition metal as catalyst. Once the catalyst is removed, the resulting material mimics the microstructure of the wood and presents high surface area, open and interconnected porosity and large pore volume, high crystallinity and good electrical...

The high temperature mechanical properties of polycrystalline Y2SiO5 were studied in compression at temperatures in the range of 1200–1400 °C, both in constant strain rate and constant stress experiments. To examine the effect of grain size on the plastic deformation, two routes were used for the synthesis and sintering of Y2SiO5: one of solid...

Bone loss is still a major problem in orthopedics. The purpose of this experimental study is to evaluate the safety and regenerative potential of a new scaffold based on a bio-ceramization process for bone regeneration in long diaphyseal defects in a sheep model. The scaffold was obtained by transformation of wood pieces into porous biomorphic...
