METHOD OF JOINING CERAMIC AND COMPOSITION MATERIALS Russian patent published in 1995 - IPC

FIELD: ceramic articles. SUBSTANCE: for joining ceramic and composition materials the surface of materials to be joined is prepared. On the prepared surface glue composition containing polycarbosilane (molecular mass is 700, not less), organic polysilane (1500), hardener dicumene, benzoyl, tert.-butyl or lauryl peroxide and filler is applied. Filler: compound taken from the group involving aluminium nitride, silicon nitride, boron nitride, silicon oxide, aluminium oxide, yttrium oxide, zirconium oxide, carbon at the following ratio of components, wt.-% polycarbosilane 5-40; organic polysilane 15-30; hardener 0.4-5.0, and powder filler the rest. Then composition is hardened in air at 100-450 C for 0.5-2.5 hr followed by thermic treatment in nitrogen or argon medium at 700-1600 C for 0.2-1.0 hr. Method is used in different branches of industry. EFFECT: improved method of joining. 3 cl, 1 tbl
