Effect of spinel content on hot strength of alumina-spinel
Nov 01 1999 · Mori et al. reported that addition of 10–30 wt alumina-rich MgO-Al 2 O 3 spinel confers superior slag resistant properties to alumina-spinel castables whose life is twice as long as high-alumina brick. The mechanism of slag resistance of the castables was thoroughly and microscopically studied by Korgul et al.
