The corrosion resistance of alumina-mullite-zircon refractories in molten glass
(Trans Tech Publications LTD, 2004)
Corrosion measurements on a set of alumina-mullite-zircon refractories have been carried out using a static crucible test consisting of a "hole in a block". Rates of corrosion of the refractory at 1370 degreesC for 72 h ...
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 ...
A Preliminary Study on Cell Wall Architecture of Titanium Foams
(Materials Research Soc, 2009)
Bio-inspired architectures, especially metallic foams, have been receiving an increasing interest for the last 10 years due to their unusual mechanical properties. Among commonly dealt foamed metals, like aluminum and ...
Chemical durability behaviour of bulk glasses in the Er-SiAlON system: Surface characterisation by SEM
(Trans Tech Publications LTD, 2004)
Er-SiAlON glasses were produced by melting appropriate powder mixtures under nitrogen at 1715 degreesC using a cation ratio composition of Er:Si:Al = 3.45:3:2 and with varying nitrogen contents (N= 5 to 22 equivalent %). ...
Investigation of parameters affecting formation of mullite from kaolin
(Trans Tech Publications LTD, 2004)
This study aims to improve the understanding of formation of mullite from kaolin at low process temperature using different sintering regimes. The optimum parameters affecting mullite formation from kaolin such as sintering ...
Formation of alpha-SiAlON ceramics containing scandium
(Trans Tech Publications LTD, 2004)
alpha-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 ...
Utilizing of borax solid wast es in roof tile and brick bodies
(Minerals, Metals & Materials Soc, 2006)
Boron minerals are widely employed in various fields such as ceramic, glass, cement, metallurgy, etc. Although boron deposits of the world are limited, the production level of boron-based products is continuously increased. ...
Development of laminar type functionally graded SiAlON ceramics
(Trans Tech Publications LTD, 2004)
In order to combine high hardness with high toughness, laminar type (two layers) functionally graded (FGM) SiAlON ceramics were developed. In a previous study achieved by the same authors, presence of a sharp transition ...
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 ...
Anisotropic sintering shrinkage in alumina ceramics containing oriented platelets
(Wiley, 2006)
The effect of oriented alpha-Al2O3 platelets on densification and shrinkage behavior of tape-cast alpha-Al2O3 during solid-state sintering was studied using dilatometric sintering shrinkage experiments and microstructural ...
