| 摘要 |
The subject of the invention is ceramic fibers for the reinforcement of refractory materials, being constituted by sintered bauxite fibers with a length/diameter greater than 10. Preferably, they have a cylindrical or prismatic shape truncated by two surfaces, for example, substantially planar surfaces perpendicular to the axis of the prism.They enable the mechanical strength and the lifetime of the refractory products to be significantly increased.
