Enhancement the crystallization and electro-magnetic properties of BaO-AlO-BO glass ceramics doped with NdO-rare earth.

In the present study, a novel glass system containing Neodymium(III) oxide with BaO, AlO, and BO were created via a popular melt-quenching technique. NdO were added, in different concentrations, instead of BO to study its impact on the crystallization, and electro-magnetic behaviors of the prepared poly-crystalline materials. Thermal characteristics via DTA, XRD and SEM techniques were involved to explore the crystallization and structural properties.

Biological and mechanical properties of an experimental glass-ionomer cement modified by partial replacement of CaO with MgO or ZnO.

Some weaknesses of conventional glass ionomer cement (GIC) as dental materials, for instance the lack of bioactive potential and poor mechanical properties, remain unsolved.Objective The purpose of this study was to investigate the effects of the partial replacement of CaO with MgO or ZnO on the mechanical and biological properties of the experimental glass ionomer cements.Material and Methods Calcium fluoro-alumino-silicate glass was prepared for an experimental glass ionomer cement by melt quenching technique.

Development of a novel aluminum-free glass ionomer cement based on magnesium/strontium-silicate glasses.

The effects of strontium substitution for magnesium in a novel aluminum-free multicomponent glass composition for glass ionomer cements (GICs) were investigated. A series of glass compositions were prepared based on SiO2-P2O5-CaO-ZnO-MgO(1-X)-SrOX-CaF2 (X=0, 0.25, 0.

Formulation and characterization of glass-ceramics based on Na2Ca2Si3O9-Ca5(PO4)3F-Mg2SiO4-system in relation to their biological activity.

Glasses having a chemical composition based on combeite [Na(2)Ca(2)Si(3)O(9)]-fluoroapatite [Ca(5)(PO(4))(3)F] and forsterite [Mg(2)SiO(4)] system were crystallized through controlled heat-treatment. Two forms of sodium calcium silicate e.g.
