| Abstract
| - The most effective treatment of toxic ashes and slags from waste incineration is the meltingprocess. Organic substances are destroyed and heavy metals partially vaporized. The productis a glassy material which is mostly resistant to leaching. Activity and mass-transfer coefficientsof minority components in synthetic slags, necessary to calculate the vaporization process, weredetermined using a top-blowing reactor. Different experiments were carried out with varyingslag composition, oxygen partial pressure, and temperature. Additionally, the slag leachingresistance was tested. The aim of the work was the development of a basis for a melting processoperating calculation.
