Physical and mechanical properties of low, ultralow and no cement refractory castables containing MgO nanoparticles developed in situ by means of polymeric resins

Abstract The introduction of MgO nanoparticles developed in situ in the matrix of high-alumina low cement, ultra-low and no cement refractory castables was made by means of a low viscosity containing aqueous polymeric resin, produced by the Pechini method.

Description
Summary:Abstract The introduction of MgO nanoparticles developed in situ in the matrix of high-alumina low cement, ultra-low and no cement refractory castables was made by means of a low viscosity containing aqueous polymeric resin, produced by the Pechini method. The addition of the liquid resin to the castables played two roles: first to serve as a supplier of mixing water and second as a precursor of nanoparticles of MgO, which were formed in situ in the castables matrices during firing. The results confirmed the benefits brought by the developed in situ MgO nanoparticles on the refractory properties of the investigated castables.
