Abstract

According to the invention there is now provided ceramic wear part comprising 2-50 % by volume whiskers and/or platelets in a ceramic matrix by powder metallurgical methods, i.e., dispersion in a suitable liquid, granulation, compaction and sintering. If the granulation is performed by freeze granulation a ceramic wear part with homogeneous structure with essentially no granule borders is obtained having a drastic reduction in wear rate.
