    Bursting of chromitic refractories (1967)
    Springer
    Refractories and industrial ceramics 8 (1967), S. 196-200 
    Details
    ISSN: 1573-9139
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Conclusions A variant of the contact method for determining bursting of refractories was developed characterizing: double sided action of tablets of iron oxide with the specimen which creates conditions for more uniform bursting of the entire specimen; observation of the changes in the thickness of the specimen during testing which permits us to control the process of bursting; control of the gaseous atmosphere (content of oxygen 14–16%); excellent reproducibility of results. Bursting of chromite-containing refractories depends on the increase in the volume of the solid phase, on the rate of its growth and the change in porosity; bursting of chromite refractories is due to the increase in the volume of the solid phase on account of the absorption of iron oxides and is accompanied by a reduction or an increase in the porosity. The growth in the volume of the solid phase of chrome-magnesite refractories, furthermore, occurs as a result of the formation of spinels.

    How corundum refractories are wetted by molten steel (1982)
    Springer
    Refractories and industrial ceramics 23 (1982), S. 504-507 
    Details
    ISSN: 1573-9139
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Conclusions We studied corundum refractories, modified with additions of Mg, Cr, and Zr oxides and silicon-containing substances designed for making the tiles of gate valves, on the wettability of steel 45 at 1550°C. It was established that within the limits studied the incorporation of oxides of Zr, Cr; mixtures of Cr, Mg and Zr oxides; and also silicon-containing additives, increases the wetting angle of corundum refractories. The low wettability of these refractories by steel to a significant degree determines the high metal resistance in service of the gate-valve tiles made on their basis.

    Wettability of refractories by molten glasses (1971)
    Springer
    Refractories and industrial ceramics 12 (1971), S. 396-402 
    Details
    ISSN: 1573-9139
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Conclusions Studies of the wettability of refractory materials lead to ideas on the degree of their destructibility by molten glasses of different compositions. The wetting angle of refractory materials depends not only on the chemical composition of the refractory and the glass, but also on the porosity of the refractory and the pore sizes. Between the wettability and corrodibility by molten window glass with one and the same temperature there is a definite connection only for separate groups of refractories; in the case of lead and borosilicate glasses this correspondence is noted also for refractories of different types.

    The chemical composition and porosity of refractories as factors in their wettability with carbon steel (1975)
    Springer
    Refractories and industrial ceramics 16 (1975), S. 174-177 
    Details
    ISSN: 1573-9139
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Conclusions In an argon atmosphere the wetting angle of aluminosilicate specimens with Steel 35 at 1550°C depends on the phase composition of the specimen, i.e., with a corundum content of 1–7% the wetting angle increases with the percent mullite in the specimen. Depending on the holding period, the wetting angle of porous corundum specimens may be larger or smaller than that of high-density substrates. Judging from the magnitude of adhesion, the stability to the chemical action of liquid Steel 35 in an argon atmosphere at a constant temperature (1550°C) should be highest for mullite. However, before recommending mullite refractories for steel-casting an investigation must be carried out of the influence of other factors occurring under production conditions.

    Effect of the structural parameters of refractories on their slag impregnation in the units used for vacuum refining of steels (1990)
    Springer
    Refractories and industrial ceramics 31 (1990), S. 543-550 
    Details
    ISSN: 1573-9139
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Conclusions We studied the effect of the specific features of the pore structure (porosity) and the wetting characteristics of the refractories on their depth of impregnation in the units used for vacuum refining of steels. The changes occurring in the pore space of the refractories during their service were examined. Minimum impregnation occurs in the materials having an insignificant content of the glass phase, a branched pore structure, and a large total volume of fine pores (in particular, pores measuring 〈1 μm in radius).
