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 ...
Synthesis of the CeO2 based pigments by using enriched rare-earth oxides located at eskişehir kizilcaören region
(2004)
Pigments based on CeO2 structure are known to give various pink-orange and red brown colour in ceramic glazes. This type of pigments is prepared by high temperature calcination of CeO2 and Pr 6O11 with admixed rare-earth ...
Gamma Attenuation Behavior of h-BN and h-BN-TiB2 Composites
(Polish Acad Sciences Inst Physics, 2014)
Hexagonal boron nitride (h-BN) and hexagonal boron nitride-titanium diboride (h-BN-TiB2) composites are advanced materials for high-tech applications. They were investigated against gamma radioisotope sources Cs-137 and ...
Reaction model for the boron carbide/aluminium system
(Trans Tech Publications LTD, 2004)
An attempt has been made to shed light on the reaction mechanism during the production of B4C/Al composites by making use of the measured phase contents of the phases B4C, Al, Al3BC and AlB2. It was found that the agreement ...
Pressureless sintering of hexagonal boron nitride powders
(Trans Tech Publications LTD, 2007)
Pressureless sintering of hexagonal boron nitride (BN) with and without additives was performed using a powder which was previously nitrided at 900 degrees C and then heat treated at 1400 degrees C. Sintering additives ...
Spark Plasma Sintering of Silicon Nitride-Boron Carbide Composites
(Trans Tech Publications LTD, 2009)
Si(3)N(4)-B(4)C composites containing fine and coarse B(4)C particles were produced using Al(2)O(3) and Y(2)O(3) as sintering additives via spark plasma sintering (SPS) technique. Phase assemblages of the produced composites ...
Application of Homogeneously Precipitated Nanosized Fe-Doped Alumina Powders to Carbon Nanotube Growth
(Wiley, 2010)
Homogeneous precipitation of hydroxides was investigated as an alternative method to synthesize Fe-doped aluminum oxide (alpha-Al2-2xFe2xO3) particles over which carbon nanotubes (CNTs) were grown via a catalytic chemical ...
