Czochralski technique (Cz) of pulling crystals from the melt is the most usable industrial method of crystal growth. In conventional Cz high-temperature gradients are used to suppress face formation. In the Nikolaev Institute of Inorganic Chemistry (NIIC) the low temperature gradients Czochralski technique (LTG Cz) was development, when temperature gradients in melt are supported at the level ~1 K/cm or less. This provides possibility to reach unique crystal perfection in combination with big crystal sizes. The main features, equipment and advantages of the LTG Cz method are demonstrated on examples of growth both laser crystals having the general formula M+R3+[Mo(W)O4]2 and scintillation crystals BGO, CWO, ZWO etc. In particularly, producing and characterization of radiation hard crystals for BELLE project at KEK Japan and for INTEGRAL, DAWN and GODDARD space projects are described.
