ABSTRACT:
The invention relates to a process of making fiber structures in the form of refractory light-weight moldings. These fiber structures exhibit the advantage that they do not contain, or contain virtually no harmful fibers, and/or that such fibers that might still exist in the fiber structures can be readily decomposed by water or body fluids. Nevertheless, the fiber structures exhibit the advantageous thermal and mechanical properties of conventional light-weight moldings. The fiber structures according to the invention are manufactured using inorganic fibers, wherein at least 90% by weight of each fiber comprises 20-50% by weight of CaO and 50-80% by weight of Al.sub.2 O.sub.3. The rest comprises a maximum of 10% by weight of typical impurity oxides. Water or a water-containing liquid is used as the charge liquid, and conventional refractory additives may also be added to the mixture of fibers and water to be molded.
