State of the art in crystallization of bulk GaN is reviewed and discussed. Fundamental physical barriers making crystal growth of GaN difficult are indicated. The Na-flux, ammonothermal and halide vapor phase epitaxy methods are presented as the most advanced and promising ones. The high nitrogen pressure solution approach developed at IHPP PAS is mentioned as a starting point of bulk GaN research.
