Pressureless Melt Infiltrated Non-Oxide Ceramic-Metal Composites
(Trans Tech Publications LTD, 2009)
In the present study highly dense (open porosity < 1 %), light-weight (d <= 2.85 g/cm(3)) and Al(4)C(3)-free non-oxide ceramic-metal composites were produced at comparatively low temperatures (<= 1250 degrees C) by pressurless ...
Microstructure-permeability relation of porous beta-Si3N4 ceramics
(Elsevier Sci LTD, 2013)
Porous beta-Si3N4 ceramics with two distinct structures were produced by using two different Si3N4 sources to investigate the relationship between microstructure and permeability. Results showed that regardless of pore ...
Spark Plasma Sintering of Translucent Dy-Y Doped alpha-SiAlON: Study of Sintering Parameters Influence on the Optical Properties by Using Taguchi Method
(Polish Acad Sciences Inst Physics, 2017)
The Taguchi approach was applied to optimize optical properties of Dy-Y doped alpha-SiAlON ceramics produced by spark plasma sintering technique. L'16 experimental design was formed according to orthogonal array. Four ...
Resonant Inspection of Ceramic Tiles
(Trans Tech Publications LTD, 2013)
For as long as there have been metal, steel and other materials, there have been methods and ways to inspect them. The efforts to improve these methods continue to be a work in progress. Non-destructive techniques are ...
The production of beta-SiAlON ceramics with low amounts of additive, at low sintering temperature
(Elsevier Sci LTD, 2010)
In the present work nano-sized powder of beta-SiAlON was produced using a wet milling process. Different milling times and mediums (methyl ethyl keton, ethanol and toluene as solvents, polyethyleneglicol, oleic acid, sodium ...
Investigation of the Improvements on Mechanical Properties and Thermal Performance of MgO-MgAl2O4 Composite Refractories by Additions of ZnO-Al2O3 to MgO
(Trans Tech Publications LTD, 2012)
The variations and developments with the reasons on the mechanical properties of MgO-MgAl2O4 and MgO-ZnO-Al2O3 composite refractories were examined and thermal parameters affecting the durability of composites at high ...
Fundamentals for optimization of binding for high refractory mullite products
(Trans Tech Publications LTD, 2004)
Properties of the binder matrix affect the quality of the refractory. Better qualities are possible if the binding is optimum. Mechanical properties, thermal shock resistance, creep and corrosion behaviour of the mullite ...
Synthesis and sintering of cordierite at low temperature from kaolin and magnesium hydroxide
(Trans Tech Publications LTD, 2004)
Thermal reactions of ultrafine Mg(OH)(2) mixtures of ultrafine particles and kaolin mixtures were investigated to obtain cordierite at low temperatures. Magnesium hydroxide was precipitated from magnesium chloride (MgCl2) ...
The use of pumice (pumicite) in transparent roof tile glaze composition
(Elsevier Sci LTD, 2006)
In this study, the use of pumice as an alternative fluxing agent instead of Na-Feldspar in the transparent roof tile glaze composition was investigated. The experiments were designed as a mixture experiment. According to ...
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 ...
