Nanomaterials for Applications in Refractory Materiais

Abstract

Refractories based on nanostructured materials are emergent technological products in several applications in the steel and cement industries. To better understand the nanostructured materials in refractories applications this chapter shows a general perspective of the use of these materials in industrial refractories. Refractories research and development based on conventional technical concepts and techniques seem to have been conducted exhaustively. If refinement of refractory technology is to be expected, the introduction of new technologies is indispensable. Nanostructured materials improve several properties of refractory materials like mechanical resistance, thermal conductive, carbon oxidation protection.

In depth studies on cementitious nanocoatings on graphite for its contribution in corrosion resistance of alumina based refractory composite

“…strength, density, resistance to thermal shock, corrosion etc. Recent literatures clarify how introduction of nanoscale materials in refractory composite enhances the surface energy, controls the rate of chemical reaction and modifies the surface and interfaces of bulk [2][3][4][5]. Selective application of nanodimensional materials thus firmly stands as a prerequisite for obtaining user friendly refractory ceramics.…”
