Abstract

Heat insulating materials having excellent heat resistance and durability prepared from glass-ceramic fibers composed chiefly of crystals, e.g., .beta.-spodumene and/or cordierite and containing 0.1 to 15% by weight of at least one metallic element capable of absorbing radiant heat energy, e.g., Cu, Co, Fe, Ni, Cr, Mn, Mg. The metallic element may be in the form of the metal or an oxide thereof and may be present as a film or coating on the fibers.
