A glass-ceramic material comprising:
- a glass phase in a proportion of at least 80.0 wt.-% and a crystalline phase in a proportion of at least 0.1 wt.-%, wherein the crystalline phase comprises a main crystal phase in a proportion of more than 50 wt.-% as compared to the total weight of the crystalline phase, wherein the main crystal phase comprises an Ilmenite solid solution with crystallites of an idealized formula Fe1-xMxTiO3 or of formula (Fe1-x,Mx)2TiO4 or (Fe1-x,Mx)Ti2O5, wherein M is selected from the group consisting of Mn, Mg, Ni, Co, Zn, Cu, Cr and combinations of two or more thereof, wherein x is in a range of from 0 to 0.80.
