AB  - Stability of aqueous and nonaqueous silicon nitride suspensions prepared in an ultrasonic bath was compared with the stability of analogous suspensions prepared by an ultrasonic disrupter. The settling velocities of the nanometric, laser driven silicon nitride powder were evaluated up to 24 h on the basis of screening sedimentation tests. It was shown that the stability of deflocculated suspensions (prepared by ultrasonic disrupter) can be predicted by the DLVO theory, whilst the stability of more agglomerated suspensions (prepared by ultrasonic bath) is to be related to the dielectric constant of the applied dispersion media.

AB  - A successful colloidal processing of ultrafine powders to produce high quality ceramic materials gives demand for stable, high degree particle dispersions. The stability of ceramic suspensions on the basis of SiC, Si3N4 and SiCN nanopowders in water and organic solvents (octane, benzene, toluene, benzyl alcohol and 1-octanole) was examined within 24 hours by means of screen sedimentation tests. Experimental results of the settling velocities were related to the calculated values of the total interaction potential energy between the particles interacting over the solvent molecules-the dispersion (van der Waals) attraction in case of organic liquids in the absence of dispersants, and a combination of dispersion attraction acid electrostatic forces in case of water, and finally to the physical properties of the used solvents.

AB  - A ternary mixture BaCO3-Al2O3-SiO2 was mechanically activated for different lengths of time. Chemical composition of the mixture corresponded to BaAl2Si2O8-BAS As a function of activation time, reaction course was followed in the temperature range 750-1200 degrees C. Reaction of celsian formation was followed using thermogravimetry as well as conventional and high-temperature X-ray diffractometry. The obtained data show that reaction rate increases with prolonged activation time, under the same conditions of thermal treatment. Formation of hexacelsian via a series of solid state reactions involving Ba-silicates, was favoured with increasing activation time. Direct formation of monoclinic celsian was retarded, however, with prolonged activation, (C) 1999 Elsevier Science S.A. All rights reserved.

AB  - The sol-gel synthesis of silicon nitride powders has been studied. The precursor gels were prepared from a colloidal dispersion of silicon dioxide and sucrose, with mole ratios of reactants, C/SiO2, ranging from 2 to 4. The carboreduction and nitridation processes were performed at temperatures between 1400-1550 degrees C under a dynamic nitrogen atmosphere, with a 4 h hold. The optimum C/SiO2 ratio and temperature for preparation of the Si3N4 powders were selected. For the SiO2-C-N-2 system examined, the boundary temperature between Si3N4 and SiC formation was established, in relation to the amount of carbon introduced.
