One of characteristic of Cr2O3-containing refractory is excellent resistance to corrosion. However, there is a problem that hexa-valent chromium, which is noxious to the human body, is easily formed by reaction between the refractory and slag with CaO, NaO2 and/or K2O. In this article, the reason why the Cr2O3-containing refractory has excellent corrosion resistance qualities, the conditions under which hexa-valent chromium formed, methods for suppressing generation of hexa-valent chromium and the possibility of the refractory components excluding Cr2O3 for the furnace are described as a base of development of further excellent refractories.
