METHOD OF PRODUCING CERAMIC COMPOSITE MATERIAL Russian patent published in 2013 - IPC C04B35/14 

FIELD: chemistry.

SUBSTANCE: invention relates to production of construction materials and is meant for producing a wide range of ceramic composite materials. The silica component used is feldspar-quartz and mica-quartz sandstones, which are ground, followed by separation of the -1+06 and -0.2+0.125 fractions and mixed in ratio of 2:1, mixed with a mineralising agent in form of cryolite and a matrix material of the following chemical composition, wt %: 69.0 SiO₂, 9.0 Al₂O₃, 2.0 Fe₂O₃, 6.0 CaO, 9.0 Na₂O and grain size smaller than 0.042 mm, prepared from bentonite and scrap glass in ratio of 1:3, with the following ratio of components of the crude mixture, wt %: feldspar-quartz and mica-quartz sandstone 52-56; cryolite 2-4; matrix material 42-44.

EFFECT: considerable improvement in operational characteristics, specifically bending strength.
