摘要： The present invention relates to an electromagnetic radiation absorbing element with a glass-ceramic with Ilmenite and/or crystallites of the formula (Fe x Mn y Mg z )TiO 3 in the crystal phase and a low volume fraction of the crystalline phase (also referred to as low crystalline phase volume) and very high optical extinction coefficient (extinction/path length) in the near ultraviolet (NUV), visible (VIS) and near infrared (NIR) spectral range. The glass-ceramic can be produced and processed with standard glass processing methods such as melting, hot forming, bending, drawing, and/or toughening (thermal and chemical). The present invention also relates to a method of producing the glass-ceramic and to the use of the glass-ceramic.
