Zinc molybdate (ZnMoO4) crystals with mass up to 1 kg of high optical quality with low levels of radioactive contamination were developed and tested (including at temperatures of 15-30 mK). The improved quality of the detectors has been achieved thanks to a new method of molybdenum purification and application of low-thermal-gradient Czochralski method to grow the crystals. For the first time the refractive index and the Debye temperature were measured with high precision. It is shown that the developed crystals are very promising material for scintillation bolometers to study neutrinoless double beta decay of isotope 100-Mo in the case of inverted neutrino mass hierarchy, and allow to develop a large-scale experiment to test the hierarchy of neutrino mass in a case of normal mass scheme.
