Optimization of alpha-sialon microstructure by heat treatment
(Trans Tech Publications LTD, 2008)
Nd-doped alpha-SiAlON starting composition (Nd(0.33)Si(9.38)Al(2.62)O(1.62)N(14.38)) was prepared by gas pressure sintering at 1825 degrees C for 3 hrs. In order to explore the effect of post heat treatment on the developments ...
Development of a multipurpose tile body: Phase and microstructural development
(Elsevier Sci LTD, 2006)
In this study, an attempt was made in order to develop a multipurpose tile body using a single formulation. In order to achieve this, several body recipes were prepared using mainly local raw materials with clearly defined ...
A comparative study of SiAlON ceramics
(Elsevier Sci LTD, 2012)
Two different varieties of Si3N4 powders were used to prepare SiAlON ceramics. 100% beta-Si3N4 was used from refractory grade powders (B1) and another purer 98% alpha-Si3N4 (50A) powder was used to prepare the SiAlON ...
Catalytic pyrolysis of biomass in inert and steam atmospheres
(Elsevier Sci LTD, 2008)
The objective of this study was to investigate thermal conversion of a perennial shrub, Euphorbia rigida biomass sample with catalyst in inert (N-2) and steam atmospheres. Experimental studies were conducted in a well swept ...
Zircon-free frits suitable for single fast-firing opaque wall tile glazes and their industrial productions
(Elsevier Sci LTD, 2009)
Wall tile glazes with a smooth surface texture, high glossiness, and whiteness are usually based on zirconium containing frits. However, these frits are quite expensive and therefore, there have recently been certain ...
The microstructural features of an alumina-mullite-zirconia refractory material corroded by molten glass
(Elsevier Sci LTD, 2003)
An alumina-mullite-zirconia refractory penetrated by a standard soda-lime-silica glass was statically tested at 1370 degreesC for 72 h. Microstructural features and EDAX analysis of the compositions in the corroded region ...
Effects of Alumina and White Fused Alumina Addition on Transparent Wall and Floor Tile Glazes
(Polish Acad Sciences Inst Physics, 2015)
In tile manufacturing, alpha-Al2O3 is the main type of alumina used in ceramic body and glaze formulations. This raw material acts as an pacifier in porcelain tile bodies and as a matting agent in glazes. White fused alumina ...
Role of alpha-SiAlON nuclei addition on the rod-like y-sm alpha-SiAlON formations
(Trans Tech Publications LTD, 2007)
In this study, effect of seed addition on the microstructural development of Y-Sm alpha-SiAION system has been investigated. Besides using pre-produced rod-like alpha-SiAION seeds, growth in the glassy phase and harvested ...
Effects of the red mud based pigment addition on the physical and micro-structural properties of porcelain tiles
(Trans Tech Publications LTD, 2004)
In the production of conventional porcelain tiles colouring agents, being either in the form of pure oxides or pigments, are commonly and widely used at considerably high amounts to increase the attraction impact of final ...
Applications of calcium phosphate based antibacterial ceramics on sanitary and tile wares
(Trans Tech Publications LTD, 2004)
In this study, metal cation consisting calcium phosphate based antibacterial ceramic powders were synthesized with wet chemical technique. The developed antibacterial powder was added to the glaze composition of the ceramic ...
