| description | A significant number of welding fluxes and industrial ceramics are produced
in the Ukraine. The production of these materials is sufficient for both
domestic needs and significant export. It is assumed that the ternary
CaO-Al2O3-SiO2 system may become the basis for the development of
agglomerated welding fluxes and technical ceramics. Three samples of ternary
CaO-Al2O3-SiO2 system were studied by means of high-temperature X-ray
diffraction above the melting point: 23.3CaO- 14.7Al2O3-62.0SiO2 wt. %
(sample 1, eutectic), 9.8CaO-19.8Al2O3-70.4SiO2 wt. % (sample 2, eutectic),
15.6 CaO- 36.5Al2O3-47.9SiO2 wt. % (sample 3). Experimental scattering
intensity curves, structure factors and the radial distribution function of
atoms were obtained. The structural parameters of short-range order were
calculated using melt structure models obtained by Reverse Monte Carlo
method. The existence of microparticle associates of the mullite or
sillimanite type immersed in the slag matrix is assumed. It is assumed that
the calcium ions coordinated aroundthese associates are surrounded by oxygen
melt anions. Such a structure can be considered as a colloidal solution. The
microparticle of mullite is the core of the aggregate that is surrounded by
calcium and oxygen ions from the molten medium. |
