摘要：
Spherical metal-oxide powder particles are used as finely ground raw and filler materials in mineral, ceramic and refractory construction, technical and auxiliary materials, as well as for polishing and grinding agents. There is a process for producing the powder particles, and there is a process for treating ceramic and refractory residual materials.
