Silica-sol bonded no cement castables have been used in the refractory industry in the last years due to some important advantages such as fast dry-out, lower open porosity, very high thermal shock resistance and excellent mechanical properties at high temperature. Binder selection plays a very important role in the phase evolution, final microstructure and ending results on the field. Some of these are absolutely important skills on metal or slag contact areas, where diffusion and corrosion phenomena are one of the main wear causes. This paper is focused on main goals to be achieved, adapting the castable formulas to special requirements in some areas of Copper, Lead and Aluminum industrial processes. Cold Crushing Strength, Hot Modulus of Rupture, Young's Modulus, Dry-out obtained by Macro Thermo-Gravimetrical Test developed by ALFRAN, Corrosion test by Aluminum alloy following several standards, are some of the properties analyzed on developed materials. Furthermore, some case studies were shown, comparing the traditional LCC castables with sol-gel NCC castables performance on the field.
