Densificaron of Sr-Mg doped SiAlONs with GPS and SPS
(2007)
At temperature above 1200°C, the thermal stability of ?-SiAlON phases has been debated since 1992; however, it has been discussed if any ?-SiAlON phase can be formed in Ce, La, Eu and Sr-doped SiAlON systems. In our previous ...
Using de-watering sieve waste of borax to enhance the properties of floor tile
(Minerals, Metals & Materials Soc, 2006)
Incorporation of de-watering sieve waste of borax (TSW) from Etibor Kirka Borax Company (Turkey) on the mechanical and physical properties of a commercial floor tile composition was investigated. In order to achieve this ...
Thermal stability of yittrium-and-neodymium-doped alpha/beta-SiAlON ceramics
(Belgian Ceramic Society, 2004)
A series of samples of yttrium and neodymium containing alpha-SiAlON (Rx+vSi12-(m+n)Alm+nOnN16-n with R = Y, Nd) has been synthesised at different temperatures and isothermal sintering times. The Rietveld technique was ...
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 ...
Optimization of ?-sialon microstructure by heat treatment
(2008)
Nd-doped ?-SiAlON starting composition (Nd0.33Si 9.38Al2.62O1.62N14.38) was prepared by gas pressure sintering at 1825°C for 3 hrs. In order to explore the effect of post heat treatment on the developments of elongated ...
The effect of boron waste in phase and microstructural development of a terracotta body during firing
(Elsevier Sci LTD, 2006)
In the present study, a dewatering sieve waste (TSW) of Etibor Kirka Borax company (Turkey) was employed in different amounts in order to develop an experimental terracotta floor tile body composition in combination with ...
Investigation of the influence of initial powder size on the optical properties of Dy-alpha-SiAlON ceramics fabricated by gas pressure sintering
(Elsevier Sci LTD, 2017)
Translucent Dy3+ doped alpha-SiAlON ceramics were successfully fabricated by the gas pressure sintering (GPS) method. The efficacy of this sintering technique also the affects initial particle size on densification, final ...
Mg+2 and Ce+3 doped ?-SiAlON ceramics
(2004)
In the present work, stabilization of MgO and CeO2 in ?-SiAlON structure is studied. Mg and CeO2 were used in 50:50 molar ratios as additives. The mixture was sintered at 1830°C for 1 hour in gas pressure sintering furnace ...
Utilization of coal combustion fly ash in terracotta bodies
(Trans Tech Publications LTD, 2004)
In this present work, coal combustion fly ash from a power plant in Turkey was used in combination with a traditional raw material in terracotta production with the aim of having a product with improved physico-mechanical ...
