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 ...

High resolution transmission electron microscopy of grain boundaries between hexagonal boron nitride grains in Si3N4-SiC particulate composites
(Wiley-V C H Verlag GMBH, 2000)
High resolution transmission electron microscope observations of grain boundaries in hexagonal boron nitride in which adjacent grains are rotated with respect to one another about either <2 (1) over bar (1) over bar 0> or ...
Novel developments in a-SiAION ceramics
(2000)
Densification and stabilization of ct-sialon ceramics have been investigated by using oxides of large cations (Sr2+, La3+, Ce3+, Nd3+) and their equimolar mixtures with calcium or ytterbium as a principal cation. All ...
Hard and tough ?-SiAION ceramics
(2000)
Yb, Nd/Ca and Ce/Ca containing a-sialon starting compositions have been densified by either pressureless sintering or capsul free sinter/HIP'ing using "conventional" ?-Si3N4 powder. X-ray diffraction studies of both ...
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 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 ...
a-SiAION ceramics densified with mixed oxide sintering additives
(2000)
Densification and stabilization of ?-sialon ceramics were investigated by using oxides of large cations (Sr2+, La3+, Ce3+, Nd3+) and their equi-molar mixtures with CaO or Yb2O3. All multi-cation and single cation (only ...
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 ...
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 ...
