摘要：
A spinel type ceramic sintered body is provided starting from a chromiferous slag which is a waste discharged from sodium chromate production, said sintered body being reproducable by selecting the mole ratios of R.sub.2 O/MgO to 0.9-2.0 and SiO.sub.2 /MgO to 1-6 wherein R represents collectively Al, Fe and Cr, the sintered body having high thermal conductivity falling within the range of 1.3-2.5 kcal/mh.degree. C., specific electric resistance falling within the range of 10.sup.2 -10.sup.7 cm high mechanical strengths and unique coloration and which can be used as a functional tile.
