ABSTRACT:
The present invention discloses a process for producing a boron nitride-coated SiC whisker, comprising dissolving a borazine represented by the following formula (I) in hexane, dispersing a SiC whisker in the resultant solution, collecting the SiC whisker thus treated by filtration, drying and baking it in a non-oxidizing atmosphere at 1000.degree. to 1800.degree. C. to form a boron nitride coating on the surface of the SiC whisker: ##STR1## wherein R is an atom or a group selected from the group consisting of Cl, N(C.sub.2 H.sub.5).sub.2, NH.sub.2, NHCH.sub.3 and CH.sub.3, and R' is an atom or a group selected from the group consisting of H and CH.sub.3.
