摘要

This paper discusses the utilization of chromium slag, which presently has no useful application in China, as a resource. The following research has been done in this paper: (1) After determining the composition and properties of chromium residue we decided to test the idea of using chromium slag as a component in synthetic MgAl_2O_4 spinel material. (2) Through experiments on sintering and electric melting of refractory materials we determined the best conditions for a practical process. (3) We compared the performance of the refractory material obtained with traditional spinel refractory materials and confirmed the excellent performance of our system. The results show the feasibility of preparing MgAl_2O_4 spinel material from chromium slag by electric melting.
