Sintering and Microwave Properties of Zirconium Tin Titanate Doped with Select Oxides
(SPRINGERNEW YORK, 2012)
Zirconium tin titanate (ZST) is often used as a dielectric resonator for the fabrication of microwave devices. Pure compositions do not sinter easily by solid state sintering; therefore, sintering ZST requires sintering ...
SnO 2 ceramics with low electrical resistivity obtained by microwave sintering
(2011-08-01)
The main aim of this study was to develop dense and conducting SnO 2 ceramics without precipitated phases on the grain boundaries, which was verified using field emission scanning microscopy (FE-SEM) coupled with an ...
Effect of atmosphere and dopants on sintering of SnO2
(2002-12-01)
Tin oxide is an n type semiconductor material with a high covalent behavior. Mass transport in this oxide depends on the surface state promoted by atmosphere or by the solid solution of aliovalent oxide doping. The sintering ...
Effects of powder preparation and sintering procedure on microstructure and dielectric properties of PLZT ceramics
(Int Inst Science Sintering (i I S S), 2003-09-01)
PLZT ceramics belong to one of the very important groups of functional materials that make a basis for the production of a large range of electronic devices. The microstructure and properties of ceramics depend on the ...
A case study of ceramic processing: Microstructural development and electrical properties of Ce0.8Gd0.2O1.9
(2020-06-01)
The effects of powder characteristics and conformation methods on green microstructure have been investigated, and microstructural evolution was analyzed based on the green density and the different sintering techniques. ...
Evolution of the fractal structure during sintering of SnO2 compacted sol-gel powder
(1995-04-28)
The structural evolution during sintering of compacted SnO2 sol-gel powder was investigated using nitrogen adsorption isotherm analysis. Results show that for sintering temperatures up to 400°C the samples have a fractal ...
Behaviour of biofuel addition on metallurgical properties of sinter
(Maney Publishing, 2009-07-01)
Blast furnace gas yield is essentially controlled by a gas-solid reaction phenomenon, which strongly influences hot metal manufacturing costs. As a result of rising prices for reducing agents on the international market, ...
Anisotropy of crystallite growth during sintering of SnO2 xerogels
(1996-12-01)
The crytallite and pore-size evolution during isothermal sintering (400 ≤ T ≤ 700°C) of SnO2 xerogels was studied by X-ray line broadening and nitrogen adsorption-desorption isotherms. The experimental results show a strong ...
Sintering of tin oxide processed by slip casting
(2000-12-01)
Sintering of SnO 2 compacts, obtained through slip casting, was studied by means of dilatometry, Hg porosimetry, scanning electron microscopy, and density measurement (Archimedes method). Sintering is strongly influenced ...
Fabrication of ZrO2-Bearing lithium-silicate glass-ceramics by pressureless sintering and spark plasma sintering
(2020-05-01)
Objective: the present study evaluated the effect of the Spark Plasma Sintering (SPS) and Pressureless Sintering (PLS) methods on the physical and mechanical properties of ZrO2-bearing Lithium Silicate (ZLS) glass-ceramics. ...
