Preparation of halide crystals

The prepared materials are chlorides, bromides and iodides (pure and doped with transition metals and rare earth metals) alkaline - Na, K, Rb, Cs, lead PbX2 (X - Cl, Br, I), double alkaline-lead - KPb2Cl5, RbPb2Cl5, RbPb2Br5, CsPbCl3, CsPbBr3, and other double alkali and transition metal halides - Cs2HfCl6, Cs2ZrCl6, etc.

The crystals are grown either by the traditional Bridgman method

or by the mentioned micro-pulling-down method. This method is adapted for preparation and growth of hygroscopic materials.
