Method of disposing of non-nuclear hazardous waste materials

摘要

A method of disposing of non-nuclear, inorganic hazardous waste materials, which method comprises compacting a sinterable hazardous waste material into a regular shape to form a hazardous waste core, coating the formed core with a glass composition or a glass precursor composition, and heating the coated core to form a fully dense or relatively low porosity, continuous, inert, water and acid insoluble, non-toxic glassy shell surrounding a fully dense or relatively low porosity core, wherein the glass shell forms a physical barrier to leaching and wherein the glass shell and the core consist of distinct phases.
