Abstract
A method of using an absorber of electromagnetic radiation, includes absorbing electromagnetic radiation with the absorber finely distributed or dissolved in a carrier material. The absorber is a crystal water-free iron(II) orthophosphate of the general formula Fe(PO)or crystal water-free iron(II) metal orthophosphate, iron(II) metal phosphonate, iron(II) metal pyrophosphate or iron(II) metal metaphosphate of the general formula FeMet(PO), where a is a number from 1 to 5, b is a number from >0 to 5, c is a number from 2.5 to 5, d is a number from 0.5 to 3 and Met represents one or more metals selected from the group consisting of Li, Na, K, Rb, Cs, Mg, Ca, Sr, Ba, the transition metals (d block), the metals and semimetals of the third, fourth and fifth main groups, and the lanthanoids or combinations of the above mentioned phosphates as absorbers of electromagnetic radiation.
