  The Center for Underground Physics (CUP) of the Institute for Basic Science
(IBS) is searching for the neutrinoless double-beta decay
(0{\nu}\b{eta}\b{eta}) of 100Mo in the molybdate crystals of the AMoRE
experiment. The experiment requires pure scintillation crystals to minimize
internal backgrounds that can affect the 0{\nu}\b{eta}\b{eta} signal. For the
last few years, we have been growing and studying Li2MoO4 crystals in a
clean-environment facility to minimize external contamination during the
crystal growth. Before growing Li2100MoO4 crystal, we have studied Li2natMoO4
crystal growth by a conventional Czochralski (CZ) grower. We grew a few
different kinds of Li2natMO4 crystals using different raw materials in a
campaign to minimize impurities. We prepared the fused Al2O3 refractories for
the growth of ingots. Purities of the grown crystals were measured with high
purity germanium detectors and by inductively coupled plasma mass spectrometry.
The results show that the Li2MoO4 crystal has purity levels suitable for
rare-event experiments. In this study, we present the growth of Li2MoO4
crystals at CUP and their purities.
