Gerk A.P. The Growth of Tungsten Carbide Monocrystals

Department of Mining, Metallurgy and Petroleum Engineering and Materials Research Laboratory University of Illinois, Urbana, February 1968. — 57 p
Tungsten carbide monocrystals have been grown from a Co flux using a modified Czochralski technique. These crystals are about 1 cm in size, show little internal strain, and contain few Co inclusionsStatement of Purpose
