Ceramic materials show excellent esthetic behavior, along with an absence of hypersensitivity, making them a possible alternative implant material in dental surgery. However, their surface properties enable only limited osseointegration compared to titanium implants. Within this study, a novel surface coating technique for enhanced osseointegration was investigated biologically and mechanically...

This paper investigated the surface reactivity of two sets of glasses and glass ceramic materials belonging to the Li2O–SiO2–CaO–P2O5–CaF2 system. The in vitro bioactivity of coatings was evaluated using simulated body fluid (SBF) and Dulbecco’s Modified Eagle’s Medium (DMEM) soaking test in static regime for up to 28 days at 36.5°C in microincubator. The surface structure changes were examined...

Vitrification is one of the technological options for treating toxic waste. This paper reports the results of the feasibility study of utilizing fly ash from municipal waste incinerators by powder sintering technology. This process was used to transform vitrified incinerated fly ash into a CaO–Al2O3–SiO2 system of glass ceramic products. The major phase exhibited is gehlenite (Ca2Al2SiO7), whic...

The joining of porous Si3N4 to dense Si3N4 ceramics has been successfully performed using mixed RE2O3 (RE = Y or Yb), Al2O3, SiO2, and α-Si3N4 powders. The results suggested that the α-Si3N4 powders partly transformed into β-SiAlON and partly dissolved into oxide glass to form oxynitride glass. Thus, composites of glass/β-SiAlON-ceramic formed in the seam of joints. Due to the capillary action ...
