Effect of different nucleation temperatures on the microstructural development of alpha-SiAlON ceramics
(Trans Tech Publications LTD, 2004)alpha-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 ... -
Synthesis of the CeO2 based pigments by using enriched rare-earth oxides located at Eskisehir Kizilcaoren region
(Trans Tech Publications LTD, 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 Pr6O11 with admixed rare-earth ... -
Utilisation of a natural stone with fluxing ability in floor tile body as a Na-feldspar replacement
(Trans Tech Publications LTD, 2004)In 1960's the floor tile production of Turkey was started with a large use of K-feldspar as a fluxing agent. However, due to its limited deposits companies begun to employ Na-feldspar instead. At present, considerable level ... -
Pressing behaviour of spray dried alumina-zirconia granules
(Trans Tech Publications LTD, 2004)In this study, spray drying of alumina-zirconia slurries on a pilot scale, and their pressing behaviour were investigated. Slurries were prepared at 50 wt-% solid loading. An acrylic polymer emulsion, polyethylene glycol, ... -
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 ... -
Use of tuncbilek thermal power plant's fly ash in stoneware glazes as a colouring agent
(Trans Tech Publications LTD, 2004)With the increased energy needs thermal power plants enlarge their production rates. In spite of high productivity in energy supplies, the concentration of fly ash filtered in the chimneys of these plants raises subsequently. ... -
Production and characterisation of pigments produced using grinding waste from cast iron foundry
(Trans Tech Publications LTD, 2004)The brown and black pigments are generally synthesised from different powders such as iron (111) and chromium (111) oxide powders. In this study, iron-chromium pigments by using grinding waste from cast iron foundry as ... -
Interactions between a bismuth type leadless glaze and a bone China body during glost firing
(Trans Tech Publications LTD, 2004)In the present study, the interactions between a high bismuth type commercial transparent leadless glaze and a biscuit fired bone china body during glost firing at different temperatures were investigated using SEM. The ... -
