A process for the preparation of a high pressure phases of boron nitride sintered article for use in the case of the cutting tools and generated by the process, the sintered article thereof

摘要

a sintered object is produced by mixing a compound (binderphase) with wbn projects, and the intermetallic compound in at least a part consists of the carbides, nitrides and boriden of elements of the groups 4a, 5a and 6a of the periodic system of elements e is selected, and at least one element from al, ni, si, co, zr and wdarauffolgendes mixing the resulting mixture with cbn and heating up the mixture produced in a 20 kbar in a can druckwert exceeding three times. as a material for cutting tools is the sintered object in its quality of the well-known sintered objects carefully.
