Spark plasma sintering of Si3N4-B4C composites
(Ceramic Soc Japan-Nippon Seramikkusu Kyokai, 2008)
In this study the production Of Si3N4-B4C Composites using spark plasma sintering technique was studied. This technique was preferred in order to minimize the reactions between starting constituents. Fully dense Si3N4 ...
Investigation of porosity of ceramic tiles by means of image analysis method
(Korean Assoc Crystal Growth, Inc, 2014)
Amount, size and distribution of porosity are among the important factors which affect physical and mechanical properties of ceramic tiles. In this study, the effect of flux variation in porcelain tile recipes and different ...
An alternative composite approach to tailor the thermoelectric performance in SiAlON and SiC
(Elsevier Sci LTD, 2017)
The thermoelectric properties of SiAlON and SiC based composites prepared by adding TiCN (5 and 10 vol.%) as a particulate or as a segregated three-dimensional network were investigated. Although the volume fraction of the ...
Effect of activators and calcination on luminescence properties of akermanite type phosphors
(Natl Inst Science Communication-Niscair, 2015)
Akermanite type Ca2MgSi2O7 phosphors activated with different types of rare earths have been synthesized through a solid state reaction method under weak reducing atmosphere and/or open atmosphere. The phase properties of ...
Optimization of the Corrosion Behavior of Mullite Refractories Against Alkali Vapor Via Zrsio4 Addition to the Binder Phase
(University Chemistry & Technology, Prague, 2009)
Effect of ZrSiO4 addition to the binder matrix of the reaction sintered mullite refractories on the alkali corrosion (Na2CO3, at 1370 degrees C) behaviour was investigated. Important improvements on the corrosion behaviour ...
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. ...
Use of borax solid wastes in diopside based glass-ceramic floor tile glazes
(Minerals, Metals & Materials Soc, 2006)
Boron raw materials are amongst the most important natural sources for many industrial branches and their values become increasingly raised with the discovery of boron usage in many new technological fields. All the countries ...
Characterization of diopside-based glass-ceramic porcelain tile glazes containing borax solid wastes
(Korean Assoc Crystal Growth, Inc, 2011)
In recent years glass-ceramic systems became industrially important for their high softening point, good coating capability for relevant substrates and high chemical and abrasion resistance. The ZrO2-CaO-MgO-SiO2 (ZrCMS) ...
The effects of re-firing process under oxidizing atmosphere and temperatures on the properties of strontium aluminate phosphors
(Pergamon-Elsevier Science LTD, 2013)
Inorganic phosphorescent pigments have a very wide application, consisting of ceramic decoration and glazes. Therefore, in the present study 3 different commercially available strontium aluminate phosphors (coded Phosphor ...
Usability of industrial ashes in cement production as pozzolanic materials
(Minerals, Metals & Materials Soc, 2006)
In the present study the utilization of coal ashes that appear at the end of firing process of brick production in cement pastes was examined. Ashes with three different particle sizes of 75 gm, 106 pm and 150 gm were used ...
