Improving thermo-mechanical properties of tabular alumina castables via using nano structured colloidal silica [PDF]

open access: yes, 2011
Great attempts were made to reduce the amount of calcium aluminate cement (CAC) content in refractory castables to improve their hot strength. Using more than 2-3 wt% CAC may cause low melting phases formation in the refractory matrix leading to weak ...
