Review on the elaboration and characterization of ceramics
Abstract One of the most important elements of furnaces boilers and other heating units is the structure (lining) usually made of silica–alumina basic or special refractories. The basic refractories are materials that are increasingly in demand and whose manufacturing involves necessarily the use of MgO and CaO. In this article the description and characterization
