The effect of heat-treatment on the performance of sub-micron SiCp-reinforced alpha-beta sialon composites .3. Mechanical properties
(Elsevier Sci LTD, 1997)
Agglomerate-free SiCp-reinforced Ln-sialon (Ln=Nd and Yb) composites were fabricated by hot-pressing and by pressureless sintering to evaluate the improvement in microstructure and mechanical properties that could be ...
Hydrated aluminium sulfate precipitation by enzyme-catalysed urea decomposition
(Elsevier Sci LTD, 2000)
Hydrated basic aluminium hydroxide precipitates were obtained from aluminium sulphate solution at room temperature and at 92 degrees C by using urea. Enzyme urease was used to decompose urea at room temperature. It was ...
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 ...
The effect of copper oxide addition and the heat treatment temperature on the microstructure of zinc containing soft porcelain crystal glazes
(IOP Publishing LTD, 2001)
In tableware industry, decorative appearance of final products is very important from the view point of attracting customers. Therefore, not only decoration patterns but also colouring is taken into account. In zinc ...
Microstructure of capacitor discharge joined SiAlON and silicon nitride ceramics
(IOP Publishing LTD, 2001)
Silicon nitride based ceramics offer great potential for industrial applications. However, the joining of Si3N4 based materials is necessary in various applications and this can be difficult to achieve. A capacitor discharge ...
Microstructural characterisation of melt infiltrated boron carbide-aluminium composites
(IOP Publishing LTD, 2001)
The microstructure of boron carbide (B4C) - aluminium (Al) composites produced by reactive infiltration were characterised using a scanning electron microscope (SEM) and a transmission electron microscope (TEM) both attached ...
Effect of cobalt oxide and copper oxide additions to zinc-containing soft porcelain glazes

Effect of electrolytes on sanitaryware slip
(Amer Ceramic Soc, 1999)
Slip viscosity is used widely in controlling ceramic casting slip. The viscosity of slip changes with the amount and type of electrolyte.
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. ...
