“…Previous works of Aneziris et al have shown favorable influences of TiO 2 on mechanical, physical, and thermomechanical properties of various carbon-bonded systems like MgO-C, Al 2 O 3 -C, and Dol-C. [27][28][29][30] However, in these works the influence of TiO 2 on the carbon content was not investigated. The doloma system is highly basic and TiO 2 must be able to adsorb the phenolic resin.…”

Doloma and doloma carbon refractories are the standard refractory systems applied in AOD (argon oxygen decarburization) and VOD (vacuum oxygen decarburization) vessels in the secondary metallurgy to produce stainless steel. This refractory system is connected with metallurgical benefits such as high oxidic stability of its oxides, and the ability to bond sulfur from the hot metal. Production and application of carbon‐bonded refractories is directly linked with environmental harmful emissions in the broadest sense. In the center of this work is the aspect of increased residual carbon content of the binder resin due to TiO2 addition. Furthermore, this work has observed the applicability of TiO2‐treated bricks in AOD converter. The increased residual carbon content of the binder resin connected with improved mechanical, physical, and thermomechanical properties due to sub‐micro scaled TiO2 and metallic antioxidant addition offers the feasibility to reduce the total carbon content without downgrading the brick properties. This aspect has not been observed yet, and is of high interest with respect to reduced emissions and environmental friendly refractories. Previous works have investigated the influence of TiO2 on other carbon‐bonded refractory systems, such as alumina carbon and magnesia carbon. As illustrated in this work and previous work, TiO2 is working completely different in the doloma carbon system when compared with other systems.

“…Among them, the following can be highlighted [4][5][6][7][8][9]: (i) the use of additives (catalytic agents) to induce carbon graphitization in thermosetting polymers, and (ii) the in situ generation of nano-structured phases due to their combination/reaction with antioxidant compounds. Increasing interest in investigating graphitizing agents is related to the fact that most of the thermosetting resins are classified as non-graphitizing carbon sources.…”

The corrosion behavior of three sorts of refractories based on alumina-graphite were studied by immersion tests. The melts included smelting reduction molten slag and corresponding carbon saturated molten iron. The influence of test temperature, FeO content in slag and specimen rotative velocity on the corrosion rate of refractories was examined. By means of SEM and EDS, the microstructure change of the refractories after immersion test in kinds of melts was studied. The morphology of the deteriorated layer showed the corrosion extent of refractories. With the addition of zirconia and titania into the refractories, the corrosion rate changed to some extent. The corrosion rate of three sorts of refractories increased dramatically with the increasing FeO content in smelting reduction slag. Compared with alumina-graphite refractory and alumina-graphite-zirconia refractory, alumina-graphite-titania refractory had stronger corrosion resistance in the smelting reduction conditions. By the results of SEM and EDS, the corrosion mechanism of refractories was developed
