Glass-ceramic glazes in the CaO-SiO2 system
(Trans Tech Publications LTD, 2004)Glass ceramic glazes were developed in the system of CaO-SiO2 system. Compositions containing B2O3 and K2O as fluxing agent were melted at 1450degreesC and fritted. Glazes for porcelain tiles were formulated by using these ... -
Materials for high performance cymbal transducers
(Springer, 2004)The effects of materials on the performance of the cymbal-type flextensional transducers were investigated under in-air and water-loaded conditions by finite element analysis (FEA) methods. At the initial stage, FEA and ... -
An investigation into bloating behaviour of bone China body during biscuit firing
(Trans Tech Publications LTD, 2004)Amongst many studies on the textural, mineralogical and physical changes during biscuit firing of whiteware bodies, this paper attempts to investigate the bloating behaviour of a commercial bone china body during biscuit ... -
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, ... -
Fast pyrolysis of sesame stalk: yields and structural analysis of bio-oil
(Elsevier Science BV, 2004)Sesame stalk pyrolysis experiments were conducted in a fixed-bed reactor in an attempt to determine the effects of pyrolysis temperature, particle size, heating rate and sweeping gas (N-2) flow rate on the product yields ... -
