Pure and chromium doped ZnO crystals were grown in a quartz ampoule with a mixture of H2+Cl2 or H2+C+H2O, applied as transporting chemical agent. Obtained by this method polycrystals were often red and had monocrystal grains of about 6x7x5 mm3. The as-grown ZnO crystals were of n-type and had low specific resistivity (about 0.05 cm at 300 K). The content of Cr in the ZnO:Cr crystals was below 1018 cm-3, which was proved by SIMS analysis.
