摘要

The method for reclaiming of ceria-based glass polishing powders from the rare earth (RE0 containing industrial wastes using thermal plasma processing of dispersed RE salts and solutions was developed. The most advantageous variant on plasma stage efficiency and on reclaiming schematic simplicity is observed to be the spray electric arc plasma processing of the concentrate nitrate solutions with surfactant. It result in as-prepared in-fluorated powders (<=55
