METHOD OF MANUFACTURING PRODUCTS FROM CERAMIC-MATRIX COMPOSITE MATERIAL Russian patent published in 2015 - IPC C04B35/573 C04B35/577 C04B35/80 

FIELD: chemistry.

SUBSTANCE: matrix from thermostable fibres is made, filled with disperse filler and impregnated with coke-forming binding agent. As dispersive filler applied are refractory metals such as B, Si, Ti, Zr, Hf, in capsule from respective nitride or without one. Then, moulding of plastic workpiece and its thermal processing in nitrogen medium at temperature of carbide and/or carbonitrides of respective metals is realised. Obtained porous workpiece is siliconised by steam-liquid phase method by capillary condensation of silicon vapour, heated to 1700-1850°C and kept in the said interval of temperatures for 1-3 hours.

EFFECT: invention provides possibility of manufacturing bulky thin-walled products without application of mechanical processing, increased reliability of their work in oxidising media at high temperatures.
