CERAMIC COMPOSITE MATERIAL Russian patent published in 2010 - IPC C04B35/80 C04B35/577 

FIELD: chemistry.

SUBSTANCE: invention relates to ceramic composite materials and can be used in aviation engineering and mechanical engineering when making heat-loaded components of gas turbine installations and engines for gas-, oil-pumping, power and transportation systems etc, used in periodic heating conditions at 1400°C. The invention discloses a ceramic composite material which contains carbon fibre and a matrix which includes silicon, carbon, silicon tetraboride, silicon carbide and additionally contains silicon dioxide, boron carbide and boric anhydride, with the following ratio of components of the matrix in wt %: Si 20-30, C 25-35, SiB₄ 1.6-1.8, SiO₂ 4-5, B₄C 1-3, B₂O₃ 0.5-2, SiC - the rest.

EFFECT: higher thermal stability and heat resistance of the ceramic composite material at operating temperature of 1400°C and retention of said properties for a long period of time (over 100 hours), which increases reliability and service life of the article.
