Crystal ZnMoO4 with enriched isotope 100Mo was developed at first time. Scintillation and bolometric properties of detectors was investigated at about 15 - 20 mK. It is shown that identification of events from random coincidences of events two-neutrino 2 -decay by shape depends mainly on the ratio of signal / noise. For the first time the contribution of random coincidences background events from gamma rays, that are emitted by surrounding materials of detector was quantitatively analyzed. Method for deep cleaning of molybdenum for crystal growth of ZnMoO4 was developed. Crystal samples with sizes 4 5 cm from deep cleaning molybdenum was obtained at first time, their bolometric properties was investigated. The influence of the addition of tungstate to the molten zinc molybdate on optical, luminescent, bolometric and scintillation properties was studied. Crystals scintillators lithium molybdate with dimensions 40 40 mm was developed; their luminescence (for the first time at the temperature of liquid helium), scintillation and bolometric properties at a temperature of about 20 mK where investigated.
