Mg+2 and Ce+3 doped ?-SiAlON ceramics
(2004)
In the present work, stabilization of MgO and CeO2 in ?-SiAlON structure is studied. Mg and CeO2 were used in 50:50 molar ratios as additives. The mixture was sintered at 1830°C for 1 hour in gas pressure sintering furnace ...
Effect of different nucleation temperatures on the microstructural development of ?-SiAlON ceramics
(2004)
?-SiAlON ceramics with elongated grains were previously observed in different studies. Sintering conditions are known to have a significant role on the microstructural development. By the nucleation treatment application ...
Microstructural evolution R-?-SiAlON ceramics (R=Y, Y+Sm and Sm)
(2004)
Yttrium or samarium doped ?-SiAlON composition was sintered using gas pressure sintering through two different sintering procedures. One group of samples was heated up to 1800°C and then held for 1h while another group of ...
Formation of ?-SiAlON ceramics containing scandium
(2004)
?-SiAlON is able to accommodate cations into its crystal structure if the cations are sufficiently small in size, thus helping to reduce the volume of the remnant grain boundary phase after processing. Lutetium with an ...
The Microstructural Studies in Limonite Containing Satin and Opaque Wall Tile Glazes
(2003)
There have been a number of studies to investigate possible use of limonite and limonite-based pigments in different ceramic glaze systems. In these researches it was reported that Eskisehir Mihaliccik region's limonite ...
Preparation of cordierite ceramics from talc with boron oxide addition
(2004)
Thermal reactions of impure materials of talc, silica and alumina with moderate particle sizes were investigated to obtain a dense cordierite ceramic by boron oxide addition as a sintering aid. Mixed powders were uniaxially ...
Microstructural evolution of mechanically alloyed and spark plasma sintered Ni-W alloy matrix composites
(2013)
Microstructural evolution of Ni(W) solid solution alloys fabricated via mechanical alloying (MA) of Ni - 30 wt.% W powders and spark plasma sintering (SPS) at 1000 C for 3 min were presented in this study. Due to contaminations ...

Characterization of microstructural and morphological properties in as-deposited Ta/NiFe/IrMn/CoFe/Ta multilayer system
(Chinese Society of Metals, 2014)
Surface morphology and its relationship with microstructure in Ta/NiFe/IrMn/CoFe/Ta multilayer system deposited by pulsed DC magnetron sputtering have been investigated in dependence of Ta buffer and NiFe seed layer ...
FMR study of ultrahigh vacuum e-beam evaporated Co 23Cu 77 nanogranular films: Magnetotransport properties
(2006)
The magnetic, magnetotransport and structural properties of Co 23Cu 77 granular thin films (7-43 nm) have been investigated using ferromagnetic resonance (FMR) and high-resolution XRD techniques. Co particles possess a ...
