In recent years, process changes that have taken place in refractories as well as ceramic industries call for use of materials which can sustain stringent conditions and provide increased life during use at minimum cost. Introduction of higher grade of special binders with the existing grade of raw materials may be a possible solution. Work has been carried out successfully to develop a number of binders, namely, calcium dialuminate cement, barium aluminate cement, magnesia based cement and develop applications of these binders along with siliceous sol, aluminium hydrate, etc. In this paper, an attempt has been made to detail out the characteristics of these new binders, improved properties obtained from the finished products after their application and finally the effect of the same in the performance.
