iron oxide

Steel corrosion processes that occur due to the effects of the biochemically treated water in coke quenching plenums have been studied. Model investigations into the processes of the corrosion failure of carbon St. 3 steel and alloyed 18Х1MF  steel were carried out to study the behavior of the  metal exposed to the action of the primary but treated water used for the coke quenching after the metal is heated to 373 K and 773 K.

The influence of iron oxides on the properties of unfluoridated enamel glass frit and coatings in the system of Na2O – B2O3– SiO2 has been studied. It has been determined that the introduction of Fe2O3 additive in the amount of 0.4 mol % instead of SiO2 into an unfluoridated glass enamels improves the optical-color characteristics of the coatings, pigmented with selenium cadmium red.
