Abstract

23225252The present invention provides for long term prevention of hydration (slaking) of CaO during a production stage during storage and during an operation stage in a refractory comprising a CaO component. That is this refractory comprises refractory particles including a CaO component and refractory particles including an MgO component where a chemical component after heating in a 1 000°C non oxidizing atmosphere contains 0.1 5.0 mass% in total of one or more species of metal oxide selected from BO TiO VO PO and SiO and 2 35 mass% of free carbon the remainder being CaO and MgO and the (CaO/MgO) mass ratio being 0.1 1.5 and where an inorganic material coating 0.1 25 µm in thickness comprising CaO and the metal oxide(s) is formed on at least the CaO surface of the refractory particles including the CaO component and/or the MgO component in room temperature microscopic observation of a sample after heating in a 1 000°C non oxidizing atmosphere.
