Chemical durability behaviour of bulk glasses in the SrO-Mn2O3Fe2O3-MgO-ZrO 2-SiO2 (SMFMZS) system
(2001)It is known that the SrO-MgO-ZrO2-SiO2 (SMZS) system glasses with 40 weight % silica content seem to give a very high chemical endurance against highly alkaline solutions and can be recommended for the reinforcement of ... -
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 ... -
Crystallisation in the SrO-MgO-ZrO2-SiO2 (SMZS) system glasses
(Kluwer Academic Publ, 2002)The SrO-MgO-ZrO2-SiO2 quaternary system was first investigated in 1989. It was reported that the lowest liquidus temperature is as similar to1000degreesC and located near the SrO-SiO2 edge of the composition tetrahedron. ... -
The Crystallography of Interphase Boundaries Between Silicon Carbide and Silicon Nitride in Silicon Nitride— Silicon Carbide Particulate Composites
(Kluwer Academic Publishers, Dordrecht, Netherlands, 2000)Interphase boundaries between 3C SiC grains and two different ß-Si3N4 morphologies in Si3N4-SiC composites have been studied by transmission electron microscopy. In general, boundaries between small ß-Si3N4 intragranular ... -
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 ... -
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 ... -
The dependence of equilibrium film thickness on grain orientation at interphase boundaries in ceramic-ceramic composites
(Elsevier Science BV, 2000)High-resolution transmission electron microscope observations of hexagonal boron nitride - 3C silicon carbide interphase boundaries suggest that where one or more phases is highly anisotropic, an orientation dependence on ... -
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 ... -
Displacement amplification of electroactive materials using the cymbal flextensional transducer
(Elsevier Science Sa, 2001)High performance electroactive materials were studied as the driver element for the "cymbal" flextensional transducer. The compositions included were commercially available Navy Type I and PKT552 lead zirconate titanate ... -
The driving force for ??ß transformation in rare earth ? sialon ceramics
(1997)In-situ ??ß sialon transformation in rare earth sialon systems, which occurs when dense ?- and ?/ß-sialon samples are heat-treated at temperatures in the range 1300-1600°C was first observed five years ago, and has generated ... -
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 ... -
Effect of ceramic processing methods on photostrictive ceramics
(Kluwer Academic Publ, 1999)Lanthanum-modified lead zirconate titanate (PLZT) ceramics (3/52/48) doped with 0.5 at.% WO3 were prepared by three different processing methods, coprecipitation, sol-gel and conventional oxide mixing techniques, to ... -
