The crystallography of interphase boundaries between silicon carbide and silicon nitride in silicon nitride - Silicon carbide particulate composites
(Kluwer Academic Publ, 2000)Interphase boundaries between 3C SiC grains and two different beta-Si3N4 morphologies in Si3N4-SiC composites have been studied by transmission electron microscopy. In general, boundaries between small beta-Si3N4 intragranular ... -
Solid-state ceramic actuator designs
(Amer Inst Aeronaut Astronaut, 2001)Smart electromeehanical systems consist mainly of sensors, actuators, and data processing units. Actuators are the responding units of many smart systems including those for active vibration control and noise control. ... -
Microstructural characterization of reactively sintered mullites
(Amer Ceramic Soc, 2000)Mullite ceramics have been produced by reaction sintering of powders prepared using pseudoboehmite-colloidal silica and aluminum sulfate-colloidal silica mixtures. The microstructural development of these mullites was ... -
Capacitor-discharge joining of oxide ceramics
(Amer Ceramic Soc, 1999)A capacitor-discharge joining technique has been used to fabricate alumina-metal-alumina and zirconia-metal-zirconia joints using thin foils of aluminum, titanium, or amorphous AlxNiyYz alloys as interlayers. The technique ... -
Cyclic crack growth behaviour of two nickel base turbine disc alloys
(Kluwer Academic Publ, 1998)The high temperature fatigue crack growth behaviour of the nickel base superalloys Alloy 718 and Rene 95 (specimen thickness = 4.1 mm) were investigated and compared with each other. Fatigue crack propagation (FCP) tests ... -
Structural analysis of bio-oils from fixed-bed pyrolysis of Euphorbia rigida and sunflower pressed bagasse
(Taylor & Francis Inc, 2000)Fixed-bed tars of Euphorbia rigida and sunflower pressed bagasse have been investigated for their structures. These mrs were fractionated into pentane-soluble and -insoluble compounds (asphaltenes). Pentane soluble were ... -
The effect of processing conditions, amount of additives and composition on the microstructures and mechanical properties of alpha-SiAlON ceramics
(Elsevier Sci LTD, 2002)A series of samples with yttrium alpha -SiAlON compositions and different amounts of additive has been fabricated from alpha -Si3N4, AIN, Al2O3 and Y2O3 starting powders, using gas pressure sintering and three different ... -
The use of waste ceramic tile in cement production
(Pergamon-Elsevier Science LTD, 2000)In ceramic tile production, because of various reasons, unsold fired products come out. These are waste tiles and only a little part of them are used. Remainings create environmental problems. If these waste tiles are used ... -
Improvement of sintering and microstructural homogeneity of a diphasic mullite
(Elsevier Sci LTD, 2001)Effect of seeding of boehmite-colloidal silica mixture with aluminium sulphate-colloidal silica mixture on its mullite formation and sintering behaviours and microstructural development was studied. It was observed that ... -
The role of fine alumina and mullite particles on the thermomechanical behaviour of alumina-mullite refractory materials
(Elsevier Science BV, 2002)Fine grain alumina and mullite particles (approximately 5 mu-m) were incorporated into slip-cast alumina - mullite refractories in order to investigate their effects on the microstructure, mechanical properties and thermal ... -
Effect of starting Si3N4 powder type and sintering conditions on grain morphology of alpha-SiAlON ceramics
(Maney Publishing, 2002)Nitrogen rich multication alpha-SiAlON ceramics doped with Y-Ce have been densified by gas pressure sintering using alpha-Si3N4 or mixed beta/alpha-Si3N4 starting powder. The effects of alpha-SiAlON nucleation and growth ... -
Effect of different starting hemihydrate powders on the performance of gypsum moulds
(Belgian Ceramic Society, 2003)In order to determine the effect of different starting hemihydrates (Plaster of Paris) on the life of gypsum moulds, microstructure of two different Plaster of Paris and gypsum moulds made from these hemihydrates have been ... -
Synthesis of an iron-chromium ceramic pigment by using limonite and chromite mixtures
(Belgian Ceramic Society, 2003)The pigments, which are important parts of ceramic industry, have been produced by a prolonged expensive process due to a necessity of using very expensive pure oxides. Therefore, it is important to produce pigments from ... -
Characterisation of biscuit fired bone china body microstructure. Part 1: XRD and SEM of crystalline phases
(Elsevier Sci LTD, 2002)As a ceramic material bone china is a highly specialised product and is the basis of the world's most attractive and expensive types of tableware, mainly due to its translucency, whiteness, bright glaze, decoration quality, ... -
Characterisation of biscuit fired bone china body microstructure. Part II: Transmission electron microscopy (TEM) of glassy matrix
(Elsevier Sci LTD, 2002)In this second part oft lie study, electron transparent specimens of the biscuit fired bone china body were prepared for a conventional transmission electron microscopy (TEM) study. The crystalline phases present in the ... -
Interactions between an ABS type leadless glaze and a biscuit fired bone china body during glost firing. Part II: investigation of interactions
(Elsevier Sci LTD, 2002)This part of the study involves the investigation of the interactions between an ABS type commercial leadless glaze and a biscuit fired bone china body during glost firing at different temperatures using XRD and SEM ... -
The effect of albite wastes on glaze properties and microstructure of soft porcelain zinc crystal glazes
(Elsevier Sci LTD, 2001)The efficient utilisation of waste materials arising from diverse industrial branches is of technological importance. As a replacement material for feldspar in some soft porcelain zinc crystal glazes, albite triage wastes ... -
Interactions between an ABS type leadless glaze and a biscuit fired bone china body during glost firing. Part I: preparation of experimental phases
(Elsevier Sci LTD, 2002)In this paper, part of an extended study, crystalline phases of a biscuit fired bone china body, namely anorthite and beta-tricalcium phosphate (beta-TCP), were produced experimentally to be used in subsequent interface ... -
Compositional modifications to floor tile glazes opacified with zircon
(I O M Communications LTD Inst Materials, 2001)In the ceramic tile industry opaque glazes with considerable zircon content are widely used. However, the high cost of zircon limits its wide use in relevant glaze compositions. In the present study, a model opaque glaze ... -
The development and characterisation of zinc crystal glazes used for Amakusa-like soft porcelains
(Elsevier Sci LTD, 2000)In porcelain production, as well as bodies expected to have white colour, compaction and translucency, suitable glaze compositions have great importance from both a technological and decoration point of view. Supplying the ...
