Biomaterials have evolved over the past three decades and are relatively specialized, highly biocompatible, but low-strength dental materials. Bioactive materials can interact with living tissues or systems. The newly emerging bioactive category of has expanded clinical uses in restorative dentistry endodontics. Examples Calcium Silicate containing Mineral Trioxide Aggregate (Portland cement); ...

Abstract Contact with groundwater in the disposal geological site will induce creation of an amorphous corrosion layer on high-level radioactive glass. This is connected to silicate saturation conditions surrounding medium, and it influenced significantly by geochemical processes near-field minerals at that depth. The international simple glass a six-oxide borosilicate commonly used nuclear int...

A new polymorph crystalline silica composition having uniform pore dimensions were synthesized by calcining a crystalline hydrated alkyl-ammonium silicate. The pore dimensions approximately were 6 angstrom for silicalite-1 and 11 angstrom for silicalite-2 units. The silicalite-1 was prepared hydrothermally at a pH of about 10 from a reaction mixture consist of water, amorphous silica and a ...

Abstract Influence of nano-glass powder on physico-mechanical properties geopolymer composite materials has been studied, in addition to studying their firing stability against high temperature from 500 up 1000 °C. For increasing mechanical, physical as well for metakaolin composites; Nano-glass was used. Alumino-silicate are kaolin, fired kaolin (metakaolin) and limestone all pass 75 µm. Mater...

Abstract — Fe2O3 substituted 45S5 bioactive glasses were prepared. Glass derived Bioactive Glass ceramics were obtained through controlled crystallization of bioactive glasses. Nucleation and crystallization regimes were determined by the parameters obtained from differential thermal analysis (DTA) of bioactive glasses. The formed crystalline phases in bioactive glass ceramics were identified u...

[1] Knowledge about the properties of silicate melts is needed by volcanologists and petrologists to evaluate the dynamics of volcanic eruptions and magmatic processes. These properties include the solubility and diffusivity of volatile components in silicate melts, silicate melt viscosity, and the fragmentation condition. Data and models of each property are reviewed and assessed. For rhyoliti...
