Role of ?-SiAlON nuclei addition on the rod-like Y-Sm ?-SiAlON formation
(2007)
In this study, effect of seed addition on the microstructural development of Y-Sm ?-SiAlON system has been investigated. Besides using pre-produced rod-like ?-SiAlON seeds, growth in the glassy phase and harvested by ...
Development strategies for sialon ceramics
(2008)
SiAlON ceramics have a wide range of applications due to their favorable mechanical and thermal properties. They are one of the main groups of materials being considered for high temperature load bearing applications and ...
Optimization of ?-sialon microstructure by heat treatment
(2008)
Nd-doped ?-SiAlON starting composition (Nd0.33Si 9.38Al2.62O1.62N14.38) was prepared by gas pressure sintering at 1825°C for 3 hrs. In order to explore the effect of post heat treatment on the developments of elongated ...
Production and industrial adaptation of fast single firing wall tile opaque glass-ceramic glazes containing borax solid wastes
(2008)
Zircon (zirconium silicate) is the main opacifier of glossy, opaque, white colored, frit-based wall tile glazes. However, zirconia containing frits employed in the preparation of these glazes increase the production cost ...
Densificaron of Sr-Mg doped SiAlONs with GPS and SPS
(2007)
At temperature above 1200°C, the thermal stability of ?-SiAlON phases has been debated since 1992; however, it has been discussed if any ?-SiAlON phase can be formed in Ce, La, Eu and Sr-doped SiAlON systems. In our previous ...
Textured ?-SiAlON ceramics via templated grain growth
(2007)
In this study, textured ?-SiAlON ceramic was produced by templated grain growth process. In order to enhance the alignment of the seeds, gated tape casting arrangement was utilized. Y-Ce codoped seeds were synthesized to ...
Proprietà Mineralogiche e technologiche di argille sotto strato di carbone provenienti dall'area di Sile (Istanbul, Turchia)
(2007)
Sile Region, northeastern Istanbul, includes the most important underday deposit of Turkey. These days are composed of disordered kaolinite, illite, mixed-layer illite-smectite, smectite, gibbsite, quartz, pyrite, anatase, ...
Effect of activators and calcination on luminescence properties of åkermanite type phosphors
(Scientific Publishers, 2015)
Ákermanite type Ca2MgSi2O7 phosphors activated with different types of rare earths have been synthesized through a solid state reaction method under weak reducing atmosphere and/or open atmosphere. The phase properties of ...
Structure, microstructure and magnetic properties of Ni 75 Fe 25 films elaborated by evaporation from nanostructured powder
(Elsevier B.V., 2015)
We report on the structural, microstructural and magnetic properties of Ni 75 Fe 25 permalloy (Py) thin films. Py thin films with different thicknesses were deposited by vacuum evaporation from nanocrystalline powder onto ...
Vibration aided vacuum infusion of bnns modified carbon Fabric/Epoxy composites
(International Committee on Composite Materials, 2017)
Two-dimensional (2D) materials have aroused remarkable attention since the successful separation of graphene, atomic layers of carbon, has demonstrated novel electronic properties. Boron nitride (BN) is a structural analog ...
