The use of an external vector action in the form of the crystal spatially inhomogeneous heating is advanced as an original and promising method of generating new properties in traditional crystals, which do not possess these properties in the thermodynamically equilibrium state, as an alternative to the universally adopted line -- the synthesis of new infrared functional materials. The change of the nature of an external influence or its direction makes it possible to control and vary the crystal polarization properties over a wide range. Tertiary pyroelectric effect is investigated which exhibits the most promising monitoring for an intense IR radiation.
