NTPF "Etalon" ltd. offers composite boride antioxidants BorTiX^® for carbon-bearing refractory materials (MgO-C, Al₂O₃-C etc.).

Carbon-bearing refractory materials are widely used in oxygen converters linings, arc furnaces, steel-teeming ladles etc. Refractory materials with carbon incorporating based on MgO, Al₂O₃ Improve their corrosion stability and thermolmechanical properties. Due to the fact that carbon has low oxidation persistence special additives-antioxidants are added into refractory materials composition. Antioxidants are added in particulates in the amount not more than 5%. As antioxidants are usually used aluminum, silicium, magnesium and their alloys, also oxygen free compounds: carbides, borides, nitrides etc. The most effective are boron-containing antioxidants. A lot of analysis made demonstrate better protective action of boron-containing additives than others. Boron-containing antioxidants possess high reducing capacity and phase change ability during oxidation-reduction reactions.

Сomposition boride antioxidants BorTiX^® are produced in a special facility by inert medium combustion synthesizing of boron-containing compounds and different kinds of metals and alloys.

Titanium, aluminum borides and others compounds formed BorTiX^® antioxidants hinder carbon oxidation within a wide range of working temperatures and lengthen refractory materials durability.
