Abstract

A refractory cement suitable as an adhesive coating for protecting metallic surfaces, as a binder for granular refractory powders and as a mortar for assembling refractory bodies has as constituents alkali metal oxide or oxides, silica and alumina the proportions of which vary from 1:1:1-1:5:1. In an example, equal molecular proportions of kaolin and potassium silicate are mixed to give a composition of K2O, Al2O3-3SiO2. A less acid cement is obtained by the addition of more hydrated alumina and a more acid one by hydrated silica. The alkali metal silicates may be added as an aqueous solution to a pulverulent silicate of alumina to form the cement as a paste ready for use.
