REFRACTORY CERAMIC MIXTURE AND BRICK MADE THEREFROM Russian patent published in 2016 - IPC C04B35/43 

FIELD: metallurgy.

SUBSTANCE: invention relates to refractory ceramic mixture, as well as to refractory ceramic brick made therefrom, and can be used for lining of cement rotary furnaces. Refractory ceramic mixture has following composition: a) 75-98 wt%, at least main initial material from group: sintered magnesium oxide, magnesium oxide, b) oxide 2-25 wt% at least granular aggregate from group: silicon carbide, silicon nitride, silicon oxycarbide, silicon oxycarbonitride, c) maximum 5 wt% of other components, each time in terms of total mixture, main initial material is in range of 10-40 wt% in grinding fraction < 125 mcm, in terms of total mixture and granular aggregate is in granulometric fraction > 125 mcm and < 2 mm. Refractory ceramic brick made from said mixture by pressing and roasting is characterised by that in it granular aggregate maximum is half-sintered with main raw material.

EFFECT: technical result of invention is obtaining articles with fire resistance higher than 1,400 °C, high resistance to corrosion and effective structural elasticity.
