Transparent ceramics are important for scientific and industrial applications because of the superior optical and mechanical properties. It has been suggested that optical transparency and mechanical strength are substantially enhanced if transparent ceramics with nano-crystals are available. However, synthesis of the highly transparent nano-crystalline ceramics has been difficult using convent...

In this paper the MBS (Magnesium borosilicate) based glass-ceramic have been prepared and characterised to find its suitability in Low temperature cofired ceramics (LTCC) technology. The glass-ceramics were prepared by using conventional solid state route. The experimental study was conducted on the MBS glass-ceramic containing MAS (Magnesium Alumino-Silicate) based glass-ceramic as an additive...

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...

This study aims to shed light on processing pathways towards functional silicate ceramics, which show some promise in various emerging applications, including dielectrics and bioactive implant materials. Polycrystalline ceramics of Neso, Soro Inosilicate families were synthesised by three different techniques: (i) a co-precipitation method, (ii) modified sol-gel method (iii) standard solid-stat...

Objective(s): Bioactive silicate ceramics have favorable features for applying as off-the-shelf bone and artificial tissue. Calcium silicate can enhance the generation of an immediate bond with host bone without an intervening rough surface in the bone layer. However, the silicate bioceramics have some drawback regarding their mechanical properties and chemical stabilities. Materials and Method...

This study investigated the influence of ceramic compositions on Knoop Hardness Number (KHN) immediately and 24 h after polymerization and the effect of activation modes on the KHN of a resin cement. Ten Panavia F 2.0 resin cement discs were activated either directly using curing light, or chemically without light, or through 1.2-thick ceramic discs. The following ceramics were evaluated: Ducer...

Doped calcium silicate ceramics (DCSCs) have recently gained immense interest as a new class of candidates for the treatment of bone defects. Although calcium phosphates and bioactive glasses have remained the mainstream of ceramic bone substitutes, their clinical use is limited by suboptimal mechanical properties. DCSCs are a class of calcium silicate ceramics which are developed through the i...

12 Background 13 Lithium di-silicate dental ceramics bonding, realized by using different resins, is strictly dependent 14 on micro-mechanical retention and chemical adhesion. The aim of this in vitro study was to 15 investigate the capability of a 1070 nm fiber laser for their surface treatment. 16 Methods 17 Samples were irradiated by a pulsed fiber laser at 1070 nm with different parameters ...

Oxynitride glasses are found as grain boundary phases in silicon nitride ceramics. They are effectively alumino-silicate glasses in which nitrogen substitutes for oxygen in the glass network, and this causes increases in glass transition and softening temperatures, viscosities (by two to three orders of magnitude), elastic moduli and microhardness. Calcium silicate-based glasses containing fluo...

Silicate ceramics are of considerable promise as high frequency dielectrics in emerging millimetre wave applications including bandwidth wireless communication and sensing. In this review, we show how quality factors low, thermally stable permittivities arise ordered silicate structures. On the basis a large number existing studies, dielectric performance is comprehensively summarized presented...
