Abstract

PURPOSE: To provide the titled compsn. giving a particularly large amount of SiC when heated at an elevated temperature in a non-oxidizing atmosphere, consisting of a mixture of a straight-chain polycarbosilane and a cyclic polycarbosilane, each having nitrogen linkages.
CONSTITUTION: An amorphous organosilicon high-molecular compd. compsn. for use in the production of SiC and having an average MW of 500W10,000 and an intrinsic viscosity of 0.01W1.50, consists of a mixture or a compound of a straight-chain polycarbosilane having nitrogen linkage and a cyclic polycarbosilane having nitrogen linkages, and gives residual SiC of 40% or higher when calcined at 800W1,500°C in a non-oxidizing atmosphere. Examples of partial structures showing the linkage between the compsn. and nitrogen atom are represented by formulasI, II and III. Pref. the amount of elementary nitrogen is 0.01W20%. When the compsn. is heated at an elevated temperature in a non- oxidizing atmosphere, it gives a particularly large amount of residual SiC.
