Isolating agent for fire polishing of white glass beads for radioactive nuclear waste glass curing and preparation of isolating agent

The invention belongs to the technical field of preparation of glass beads, and provides a parting agent for fire polishing of white glass beads for radioactive nuclear waste glass curing and preparation of the parting agent. The invention provides a parting agent for fire polishing of white glass beads for radioactive nuclear waste glass solidification. The parting agent comprises the following components in percentage by mass: 10-70% of alumina powder, 20-90% of quartz sand, 1-3% of cerium oxide powder and 1-6% of white flour. According to the parting agent disclosed by the invention, the white flour is introduced, so that the color of white beads can be protected, the appearance of fire-polished glass bead products such as twins and trips in the fire-polishing process of the glass beads can be avoided, meanwhile, main chemical elements in the parting process are prevented from being introduced to the surfaces of the glass bead products, and the component stability of the glass bead products is improved. 本发
