Glass microspheres with the exact stoichiometry of åkermanite (Ca2MgSi2O7), one most promising modern bioceramics, were produced by flame synthesis method. The distinctive high cooling rate was found to prevent crystallization; size amorphous microbeads could be correlated partially crystallized precursor powders, deriving from conventional melt quenching and milling. glass characterized in ter...

A new method for the vitrification of pure liquid water anddilute aqueous solutions is described which works as the only one without liquidcryomedium for heat transfer : rapid rooling of aqueous aerosol droplets on a solidcryoplate (1). The method can be applied in diverse fields such as cryobiology,crymicrosco~and low temperature spectroscopy of water and aqueous solutions ...

Containerless melting was employed to evaluate the influence of increasing ZrO2 additions on glass-forming ability peraluminous melts in magnesium aluminosilicate system. The saturation limit this oxide glasses along silica-cordierite join (SiO2–Mg2Al4Si5O18) is inversely proportional SiO2 content; however, a limited solubility melt-quenched silica exists (∼2 mol%). Peraluminous samples (partic...
